Ovulation Calculators Help Determine Baby Making Time

Want to Get Pregnant? Use a Calculator

If you want to get pregnant and you're not sure where to start, a good first step is getting familiar with your body.

Pin pointing your ovulation time frame can be key. You can do the math yourself but like 9th grade algebra, a calculator makes it easier. To find out how,


On sites like BabyHopes and WebMD, simply enter the first day of your last period and how many days are in your cycle (usually 28) and your probable ovulation dates will reveal themselves. Some calculators, like the one on, will even show you the astrological sign that corresponds with the baby's approximate due date. So if you don't want a Scorpion baby, then you'll know to save the baby making for next month!

Obviously, there are other factors that play a role in the whole baby making process, but knowing your body is a good starting point.

Good luck!

I found a cool one at moms that think that tells you if you have a higher chance of having a boy or a girl. It's actually right for my soon to be new DS.

When I got pregnant - I followed one of these calculators and got it right the first month. I was also using ovulation predictors that I bought in a store that you use from like days 10-20 and it indicates when you are fertile.

Wow, really? I thought it was always bang in the middle. That may explain why I'm still not pregnant, as I tend to be like, okay honey, that's it for the month!

Ditto. I temped when we were trying. I ovulated on day 21 of a 28 day cycle. None of the online "calculators" were correct for me, they were a week off!

i just started using the fertility awareness method (FAM)--i highly advise every woman get her hands on a copy of 'taking charge of your fertility' whether she wants to achieve pregnancy, avoid pregnancy, or just be aware of her gynecological health. it is much more reliable than just plugging in your data into one of those calculators, because every woman is different and her cycles can vary, too!

That method is not predictable, I've used NFP to both avoid pregnancy and to get pregnant for a number of years, everyone's cycles are different as are their luteal phase. The book taking charge of your fertility explains a woman's cycle in depth, also websites such as fertility friend and oversoft are a great place to start.

If you want to figure out when you are ovulating, definately get a basal body thermomenter, like cine_lover said. But also, start doing the other part of the symptothermal method (NFP). You've got to be comfortable with feeling your own cervix, but if you can get past that, it's really easy to figure out what's going on with your cycle and which days are best if you're trying to get pregnant.

I used the WebMD calculator, and my high fertility date is Valentine's Day. :bcbw: :rotfl:

This method does not work for most people. If you want to know when you are ovulating get a basil body thermometer, and start to track your cycles and your symptoms.
