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.

  6. Olivia says:

    Hi, do you know when you ovulated?

    There is always the chance of either gender when you do get pregnant, though natural gender selection methods can swing the odds in your favor. That means if you are pregnant, of course it is very possible you will have a boy.

  13. ANCY says:

    i am 33 years, my last periods 7,8,9 irregular periods. but how can ovulation date ? i am trying to get baby . is there any chances to conceive?

  14. Olivia says:

    For irregular periods, I advise ovulation tests. These react to luteinizing hormone, and when an ovulation test comes up positive, you can be certain you are ovulating.

  19. Olivia says:

    Hi Anitha,

    I don’t know how long you have been trying to get pregnant, but it is normal for healthy and fertile couples to take up to a year to get pregnant. Even if you do everything right, some part of the conception process is simply left to chance — a fertilized egg simply doesn’t happen every time you get the timing right. How long have you been trying in total now? Do you have any reasons to suspect you may have fertility problems? If not, I’d advise you to keep on trying, and also to take folic acid and a good multivitamin supplement (your husband too!).

  20. anitha says:

    hi Olivia, thanQ very much for your quick reply. i have been trying for 2 months only that is from jan 2012. and i forgot to tell u..i have one daughter also. she is 7 years old. after long time we are trying for 2nd. in between i have undergone abortion also in the year 2007. is abortion reason for not getting pregnancy? after first delevery (c section) i became fat also. thats why i am worrying after i got periods yesterday. should i meet doctor??? thanks for reply and take care

  24. Carly says:

    Hiya, I’m just looking for advice really.
    I am already a mum and my youngest is 21 mths old but despite not using any form of contraception and calculating my expected ovulation days & fertile days and doing ” the deed” I still haven’t conceived! I’m 28 so age shouldn’t be a factor and there are no other possible health issues to explain it!! Any help would be great!

  31. Nusrat says:

    I have abortion on 15th Februray and have bleeding for 10 days What will be ovulation days.

  32. Olivia says:

    After a miscsarriage or abortion, your cycle can be irregular for a while. If you do not want to get pregnant, it is best to use a reliable contraceptive. If you do want to get pregnant, it is best to wait for a few cycles.

  33. ms curious says:

    as i remember my last period was sept 24,2011 and after 3 days i had a sex wth my boyfriend wch i dont know if am fertile or not.coz my period become not regular..tht was when my husbad was away wth me..unexpectedly my husband came and we had a terible sex on oct 17 which i guess tht i am fretile..so by this after a week i test n pregnancy test and i was positive..then after 4 months i visit my gynaelogy and by using only stethoscope she said am 5 months pregnant maybe,,,not sure as shes not used an ultarsound..so my question is does the gynaelogist can detect the month of my pregnancy accurately wthout using the ultrasound…am afraid i might be pregnant wth my boyfriend and not wth my husband pls advice..i am 35 years old..

  34. lakshi says:

    hi Olivia, im 27 & my hus 31.i have expected pregnancy. i have planned according to ovulation calender only.December, January, February i tried. but this month also i had periods . what i have to do? any problem with me?

  35. Olivia says:

    We can’t, of course, diagnose any problems or declare you and your husband healthy from the internet. One good way of knowing whether you ovulate is to use ovulation tests on the days surrounding your expected ovulation. If you ovulate, that is a very good sign. Lots of couples try for six months to a year before conceiving, so your situation is not worrisome at the moment.
