ovulation calculator

If you want to have a baby, you can try to speed up the process by using tools such as CaptainMums’ Ovulation Calculator.

And why would you need it, you say? Well, the monthly window of opportunity for getting pregnant is not open as much as you may think – the egg produced by your ovary only lives from 12 to 24 hours! Considering this fact, you may start to understand why knowing the exact day you’re ovulating is important for any ‘wannabe’ mummy – and this is where the ovulation calculator makes its entrance.

You can find out which days you’re ovulating by measuring your basal body temperature or using ovulation sticks (or both!), but CaptainMums can also give you a hand with our Ovulation Calculator: an easy and free method to calculate when your egg is ready to be fertilised!


How to use the Ovulation Calculator

The Ovulation Calculator is a great tool to know when it’s time to try to get pregnant if you have regular periods. You only need to introduce the first day of your last period and the number of days your menstruation cycle lasts. Usually, the menstruation cycle lasts 28 days, but it can change from one woman to another. Some women have shorter cycles of 26 or 27 days, and some other have longer ones. If you don’t know how many days is yours, count from the first day of your last menstruation to the day before the next one starts. It’s always useful to keep an ovulation calendar (also called fertility calendar), even if you’re not completely regular: If your cycles vary only a few days, you can still try to calculate ovulation and consider a wider window of opportunity.


If I’m not regular, when am I ovulating?

If you have irregular periods, there are other ways you can find out exactly when you are ovulating. First of all, you could try to read the symptoms, which are:

  • Thicker vaginal discharges, whiter than normal
  • Increase of the libido, that is, more sexual desire
  • Your vagina and vulva could be a bit swollen
  • Abdominal pain, similar to period cramps
  • Sensitive or sore breasts
  • Liquid retention or swollen lower abdomen
  • Moodiness


However, as in everything related to the reproductive system, symptoms can vary and not all women have the same ones. Some lucky ones don’t feel anything and some others suffer from all of them – and they can change throughout a woman’s fertile life too. If you don’t feel any symptoms or you have an irregular cycle, your best option might be turning to ovulation sticks.

Getting pregnant can be a difficult and stressing process, so it’s always better to use all the tools available. The Ovulation Calculator is effective for women with regular cycles, but if yours is somewhat irregular, giving it a try can’t hurt either!
