    • Ovulation period calculator elevates the  chances to conceive naturally as you get to know your exact ovulation date.
    • Ovulation is the process of mature eggs reaching fallopian tube to fertilize. It usually starts 14-17 days before the following menstrual cycle. However use the Ela Ovulation App to know your OD with an accuracy of 96.9% - highest in the industry.
    • On average Ovulation Period lasts for five days. This cycle is termed as ‘fertile window’. It shows the life-span for sperm ( 5 days ) and ovum.
    • Ovulation Period for every woman is different because of the variation in the individual menstrual cycle.

    2. How does an Ovulation Calculator work?

    • If you go with the  technique, pregnancy is possible starting from three days before the Ovulation Day and until a day later than ovulation day.
    • Fertile window closes after 12 to 24 hours of Ovulation period. The chances of pregnancy decline as soon as fertile window gets closed. Fertilization takes place in the Ovulation Period only.
    • An Ovulation Calculator checks your ovulation period which you can mark on your ovulation calendar.
    • You need to mark First Day of your last period on a simple paper calendar and mark the days for which it continued. This will work as an Ovulation or Period Calculator. You can also use the Ela Ovulation App.
    • Now, count the number of days you normally have your menstrual cycle like for 28 days or 31 days. On Ovulation Calendar, mark the day when your next period will commence, following the cycle you regularly have.
    • Ovulation period will start 2 weeks before the following periods. For instance, if you have your next periods scheduled on 28th of the month, your ovulation period will start around 14th or 15th of the month. You can also use the Ela Ovulation App, which is completely free.
    • An Ovulation Calculator also works like a Period Calculator as it keeps an eye on your menstrual cycles as well.

    3. Why to use Ovulation Calculator?
