To use ovulation calendar you need to enter:

- The first day of your last period: this means the first day of your last menstrual flow.
- The length of your menstrual cycle:  the number of days from the first day of menstruation to the day before the following menstrual period starts.
- The length of your luteal phase:  if you don’t know the length of your luteal phase, you can assume it’s 14 days.

 

How to read this ovulation calendar?

Red indicates blood – menstrual flow:

Dates that are colored red represent the section of the month when your period starts. The first day is labeled with the darkest red, because this is usually the day menstrual flow is the heaviest. On average, a woman’s menstrual flow lasts from three to five days. Usually on the first day, the bleeding is the heaviest, and then it slowly subsides.

Green indicates fertility – ovulation:

Dates that are colored green represent the section of the month when you are most fertile –  the time around your ovulation. The darkest green is labeled as THE ovulation day and this is the time you are considered most fertile. Since a woman’s fertile period starts about four to five days before actual ovulation, and ends approximately  24 to 48 hours afterward, there are several days that are colored green. All these days have a potential if you are trying to conceive.

Gender selection:

According to the Shettles method, it is possible to determine a baby’s gender by timing your intercourse. The dark gray frame around the ovulation calendar dates determines the dates that are most appropriate for conceiving. If you would like to conceive a baby boy, the frames will appear around your ovulation day, but if you would like to conceive a baby girl, a frame will appear on the days preceding actual ovulation. If you have no preference regarding the gender of your baby, no frame will appear.

How do I calculate my fertile days using our free ovulation calendar?

You do not have to do any math – our ovulation calendar will do all the work for you! Based on your menstrual cycle data, our free ovulation calendar calculates your fertile aka ovulation days.

To use ovulation calendars you need to enter:

  • The first day of your last period: this means the first day of your last menstrual flow.
  • The length of your menstrual cycle the number of days from the first day of menstruation to the day before the following menstrual period starts.
  • The length of your luteal phase AKA “days past ovulation” or “DPO”, is the part of the cycle that starts at ovulation and ends the day before your next period. The only way to determine the exact length of your luteal phase is through hormone-specific blood tests. If you are not sure about the length of your luteal phase, you can assume it is 14 days, which is the average length and does not vary by more than a day or two in most people.

Based on the data given, the free ovulation calendar generates your personal daily fertility chart.

For example, if your cycle is 29 days long and your luteal phase is 12 days long,  ovulation will occur on day 17 of your cycle (29-12=17).  Ovulation calendars use this formula to calculate your time of ovulation.

If you have a gender preference, simply select boy or girl from the gender field. The method used for gender selection is called the Shettles method. Dr Landrum Shettles claimed a 75 to 90 percent success rate for his simple at-home method, which advises how to time intercourse to conceive a boy or a girl.

**The Shettles Method is based on a theory of X and Y chromosomes. X chromosomes represent a girl and Y represent a boy. His theory is said to have 75 percent success rate with couples who want to determine baby’s sex, although as already said it should be taken with a bit of healthy skepticism.

The basic principle behind his theory claims that Y chromosomes (for those who want to conceive a baby boy) are smaller and more fragile, but faster comparing to X chromosomes that are slower, but also larger and more resilient and are able to survive longer when they are once released.

**What is ovulation?

The time of ovulation is one of the most important things a woman should understand about her body since it is the determining factor in getting pregnant and preventing pregnancy. Ovulation is the most fertile period of menstrual cycle – it is a period when woman is most likely to get pregnant or when the chances of conception are the highest. Woman’s fertile period starts about 4-5 days before ovulation, and ends about 24-48 hours after it.

**What happens during ovulation?

During ovulation a single, mature egg (aka ovum) that developed in the ovary during the menstrual cycle is released from a follicle. When the egg is released, it is capable of being fertilized for 12 to 24 hours, and then it begins to disintegrate. Ovulation usually happens in the middle of the menstrual cycle, and if the released egg (ovum) is fertilized and successfully implants, woman becomes pregnant. However, if the egg isn’t fertilized and if woman does not become pregnant, the egg is passed from the reproductive tract during menstrual bleeding, which starts about two weeks after ovulation.

However, sometimes anovulatory cycles happen. These are menstrual cycles when no egg is released but when a woman does have her period. On the other, it is also important to bring out that woman can their get period (meaning menstrual flow does occur), but she does not ovulate. The ability to ovulate does vary from month to month, and can be delayed by a number of factors such as stress, illness, diet, or increased physical activity.

**What happens in the ovaries?

Woman has two ovaries and each produces many eggs during one menstrual cycle (which usually lasts approximately one month). Largest of the eggs is expelled into the pelvic cavity and swept into the Fallopian tube. There is no regular pattern between ovaries and it is fairly arbitrary which ovary will release the eggs.

**Explaining Ovulation with Hormones

Two hormones which create conditions conducive to fertilization are produced during ovulation: oestradiol and progesterone.

Oestradiol is produced alone by the developing follicle before ovulation and it stimulates the glands of the cervix to secrete fertile mucus and to stimulate the growth of the endometrium lining the uterus.

After ovulation, both oestradiol and progesterone are produced by the corpus luteum which forms from the ruptured follicle. Progesterone causes the abrupt change in the mucus which occurs immediately after ovulation and defines the Peak symptom. This hormone also prepares the oestrogen-primed endometrium for implantation of the fertilized ovum.

    Hi, Ive been trying to conceive a baby girl (accordinlg to specific dates as per the calender) but 1st I was not ovulating and now we have discovered that my husband has low sperm count – 8 million. we have tried again this month and doctors have certiied that Im ok (ovulating). Can we conceive with this number of sperm? Any other advises will be appreciated.

  3. Olivia says:

    Do you know the reason you were not ovulating? Were there any underlying medical conditions? Did you get any medication, such as Clomid? It is possible to conceive with low sperm count, but it does pose more of a challenge. I suggest you look into natural methods of boosting your husband’s sperm count, to see if that will make a difference for you.

    Good luck! I’ll write something about conceiving with a low sperm count one of these days!

  8. Olivia says:

    Hi Kerryn,

    Are you using ovulation predictor kits as well as the ovulation calendar? Are you sure that you are ovulating when you think you are, and that you are ovulating at all? If the answer to all of these questions is yes, the chances are that you will conceive very soon! How many cycles have you been trying for a baby now? Sending you lots of baby vibes :) .

    Hey Chantal.

    I hope you are doing fine…

    there are things that can contribute to conceiving, such as smoking, caffeine, alcohol etc.. and I am sure you are well informed about that.

    … there are several types of ovarian cysts and not all interfere with the ability of trying to conceive…

    Did you ever talk with your doctor about that?

  11. vicky says:

    hi….. im using fertilite kit past 2 days. but its shows negative. what should i do?

  12. Angela says:

    Hi

    I too am trying to conceive and it is ruling my life right now. I was recently diagnosed with endometriosis and my partner has slightly lower sperm count of around 13million but with normal motility. We have received our appointment for the fertility clinic for next month but I feel I am putting my partner under a lot of pressure. He is working away at the moment but has to return for “our best time” even when this causes him problems at work.

    My last af was 23/7/10 and had positive ovulation test yesterday and today but he could not get back until tomorrow now. We did have intercourse on Sunday and Monday I am just really hoping this time was still ok? Also he would love a daughter and I heard it was more chance if have intercourse earlier rather than right on ovulation?

    I feel like I am becoming crazy constantly looking at calenders etc.

    Hi Angela.

    I hope you are doing fine… and stress is a lot of times a part of process of trying to conceive, especially if things aren’t working out as planned. The only thing that I can say is .. try to relax… I know – easier said than done…

    About conceiving a girl – yes, according to Shettles method this is true (you can find more about the method in the text above).

    My best,
    Tanya

    Hi, how useful is this calendar or the Shettles method if you have irregular periods? How do you get around the fact that you never know when ovulation will happen when you’re trying to conceive a girl? Thanks!

    Have you seen endocrinologist? if you are younger than 35, and trying to conceive for more than one year (older than 35 and TTC for 6 months) you and your partner should consider visit a specialist. My best!

  34. Fibbie says:

    hi I have type 2 diabetes and am trying to conceive for about a year.. I wanted to know am is it possible for me to have a baby? Or is it much hard to because of my diabetes does it take away anything as if someone without diabetes.. I been with my boifriend for five year but we just decided now was a good time. But were haven no success pretty hurful.. Thanks for sum help!! :(

  35. Jenny says:

    It took my husband and I 6 months to conceive. At the time it seemed like it was taking an eternity. We lost that baby at 9 weeks. After the loss I felt like all my hard work was just thrown away. I have several friends who ended up being pregnant at the same time as me. They were fortunate enough to keep theirs. Now every time I see them it reminds me that I should be pregnant; not to mention every time I get my period. I feel like a crazy person. It has been 3 months since the loss and still no luck. Everyone says it will happen when the time is right. I guess the part I hate the most is feeling like I have no control over any of it. I see people who don’t want children get pregnant by mistake all the time. It happens every day all over the world. It didn’t seem like it should be this hard. As a female when you experience difficulties in the thing our bodies were made to do it makes you feel like less of a woman; a failure. I frequent the ovulation calendars often but I haven’t had luck with any of it. My husband says I’m stressing too much over it. LIfe is unpredictable so I should just go with it. Wish it were as easy to do as it is to say it.

  36. Diana says:

    Hi everyone, I was wondering if I am having sex during around my ovulation time, can I still pregnant if my bf and I do the pullout method?

  37. admin says:

    @Diana: of course… the chances are smaller if you are using the pullout method, but yes you can get pregnant – only one little swimmer is needed for that :)

  38. Josephine says:

    Hi. I have regular period but this month my period came after 24 days and we are trying for a boy. So when should I have sex? Should I calculate my ovulation days based on 24 and luteal days of 12 or should I calculate based on the my past period where they are coming after every 28 days. Please help so I can travel to where my husband is.pleeeeeeeeeeeeese

    Me and my bf has been trying to conceive for almost 2 years on our own. My period started 11/4 I finally seen a dr @ which he prescribed Clomid and I start my 5 for 5 today. Has anyone heard of the success stories or not so great stories of Clomid? I am very healthy 35 year old as is my 43 year old bf.

    I was advised that the success rate may take about 3 months some sooner once they start the Clomid. PLease let me know if anyone can provide me with any great details on becoming pg.

    Hi I did a blood test on the 18th my period is supposed to start on the 23rd. The test results came back negative. Is it possible to get a false negative because i was 5days away from my period with a blood test?

  49. Maya says:

    @Jenny
    I am in the exact shoes. Just reading your comment made me burst into tears. Hang in there and know that you are not alone. I too lost my baby at 12 weeks, had a D & C, had complications post D & C and didn’t get my 1st period until 2 months later… and EVERyone, including our cousins are pregnant, they got pregnant after me and are successfully carrying theire baby-Thank God and I am happy for them! Me not being able to the same(carry my baby successfully) makes me feel like a complete failure. One of our friends-a couple-got pregnant the same time and our due dates were around the same time. We haven’t talked to them since we lost our baby b/c its soo hard. Seeing others pregnant reminds you of what you lost and where in your pregnancy you should have been at. Hang in there. Take comfort in the fact that you are not alone. May God bless you and your hubby with BEAUTIFUL babies SOON!
