Ovulation Calculator: When Is Your Best Time to Try and Get Pregnant?

Ovulation is when a mature ovarian follicle (part of the ovary) releases an egg (also known as an ovum, oocyte, or female gamete) and travels down the fallopian tube where it is made available to be fertilised by a sperm.

When trying to get pregnant, knowing when you ovulate can enable you to focus your conception attempts around this time to help maximise your chances of getting pregnant.

The Ovulation Calculator helps you predict your most fertile days of the month. As you already know, the menstrual periods vary from woman to woman and month to month. Use the Ovulation Calculator to increase your chances of getting pregnant by helping you determine the timing of your ovulation and peak fertility.

The Ovulation Calculator will show you your most fertile dates based on your last period date and your period length. Find out when your next period is expected to start, when you are likely to ovulate and increase your chances of getting pregnant.

Did you know?

Many women do not have 28 day cycles. The ovulation window is unique to each woman, therefore if two women share the same cycle length they may ovulate at different times. This is important to know, so you can also plan conception attempts at the right time for your cycle. Other facts include:

 

  • On average, women are born with around two million immature eggs that are awaiting ovulation. Unlike sperm, women have a finite number of eggs.
  • Usually one egg is released each time you ovulate.
  • An egg usually lives around 12-24 hours after leaving the ovary.
  • Ovulation can be affected by illness, stress, travel and other issues such as poor hormonal feedback, PCOS and ovarian trauma.
  • Implantation of a fertilised egg usually takes place around 6-12 days after ovulation.
  • Menstruation can still occur even if you haven’t ovulated.

Use our fertility calculator to calculate your most fertile days of the month. Fill in your Last Menstrual Period (LMP) date – the first day of your menstrual period is considered to be day 1 in your cycle -, your cycle length and your email to receive most of the important dates of your pregnancy.



No need to purchase special kits!

Our aim is to empower women to become more aware of their own cycle and to better understand their bodies and when they are likely to be ovulating.

There are a number of ways to assess and predict when you may be ovulating. Our calendar is a great first step at gauging this important biological process. Women’s cycles are complicated! Let us help you to try and make sense of it all.

At Foresight we also highly recommend the Natural Family Planning (NFP) method of charting your cycle, which offers an invaluable insight and includes monitoring your body temperature and cervical mucus to become more in tune with your own body. NFP offers invaluable insight for individuals and couples experiencing fertility issues, breastfeeding mothers and for couples seeking non-invasive contraception.

Natural Family Planning (NFP) Fertility Facts 

  1. A woman produces usually only one egg per cycle which is fertilisable for no more than 12 hours after release.
  2. That for about 6 days before ovulation, the cervix opens and produces a fertile mucus secretion which keeps sperm alive for 3-6 days, enabling them to survive inside the woman until the egg is released.
  3. During these six days the mucus is alkaline; the remainder of the cycle the mucus is acidic which is hostile to sperm and they cannot survive in it.
  4. That a woman is fertile due to this mucus for about 6 days before ovulation and only 2 days after, allowing for the release and life of the egg.
  5. That all the rest of the time she is infertile because the cervix is sealed with a sticky mucus plug which blocks the passage of sperm.
