Fertility Calculator: Find Your Ovulation Date

The key to getting pregnant is knowing when you ovulate. Use this free fertility calculator to help determine when you will ovulate this month, or try one of the other ways to pinpoint ovulation as shown below.

If you are trying to conceive a child, the first thing you should know is the date of your ovulation, the optimal time for you to have the maximum chances at conception. There are a couple of ways to find out when you are ovulating, and you can do it yourself, at home, with a fertility calculator, without going to a doctor every month. Here are a few methods of finding out when you are ovulating: Claim Your 20 Free Pregnancy Tests – Click Here

Fertility calculator

A most convenient way of finding out when you ovulate is to use a fertility calculator, like the one above. You enter the first day of your last cycle and the number of days your menstruation usually lasts (it is normally between 21 and 35 days) and a computer will show you the days when you are ovulating. Nonetheless, though this is a very simple method, you cannot trust it 100%, as it does not consider your personal issues which influence ovulation. But it is a fairly good place to start, to give you a more accurate guesstimate than just trying to have intercourse all the month long.

Ovulation predictor kits

Probably the easiest way is to know when you are ovulating is to use ovulation kits, which you can find in any pharmacy or drug store. They are very fast and easy to use, and they are over 90% accurate, so you can be almost sure that they are correct. Just like a pregnancy test, you pee on the stick and wait for 2 lines to show, both the Test & Control lines. Ovulation predictor kits sense when there is luteinizing hormone (LH) in your urine, which is present 24-48 hours prior to ovulation. So once you get a positive OPK, it’s time to get busy.

Chart your basal body temperature

Another way to find out when you are ovulating is by determining your basal body temperature. For a whole month, every morning, before getting out of bed, you should determine your body temperature by using a small thermometer. It is easy and 100% accurate, but you do have to take your temperature every day during an entire month. In the days when you have a slightly higher body temperature, you know you are ovulating. However, you can only do this if you have regular menstruation. Remember the days of ovulation, so that you will know for the next month where in your cycle you ovulate.

Ovulation calendar

An even easier way to know when you are ovulating is to look at the calendar. You should be ovulating halfway through a menstrual cycle, about 14 days after the first day of your last menstruation, give or take 2 days. However, this is not really a very accurate method, so consider one of the above if you want to know precisely.

If you are considering getting pregnant, the best thing is to ask for a doctor’s opinion. Make an appointment and get the best advice for you.

    Yes, having intercourse during your fertile days will likely get you pregnant.

    I do recommend you Fertibella ConceiveEasy, given that it can increase chances of having multiples, for it is designed to stimulate ovulation. Other fertility drugs that may help you increase your chances of conceiving twins may also include Clomiphene and Parlodel. It is best that you initially consult your ObGyn, in order for you to determine if these pills are safe for you to take.
