**Legend

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 ovulation calendar?

You don’t have to calculate anything – the ovulation calendar will do all the work for you! This ovulation calendar calculates your fertile days based on your menstrual cycle data.

To use the 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:  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 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).  The ovulation calendar uses 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.

  4. 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!

  13. 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?

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

  17. 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!
