The Ovulation Calculator provides the estimation of your fertile window. The chances of a woman getting pregnant are more around this time. Typically the menstrual cycle in a woman is 28 days. Each woman is different and so this cycle gets shortened or lengthened accordingly and the ovulation window depends upon this cycle. There are around 6 days during each menstrual cycle when the chances of a woman getting pregnant are highest. It is the process by which ovarian follicles break and release one or more mature eggs from the ovaries.

The calculator is helpful in finding out the days when you are most fertile. Though it does not guarantee either pregnancy or birth control, it surely can be used to plan your pregnancy or for birth control purposes. Even for the same woman, the fertile window can differ from month to month. The fertile window means the day when you ovulate and five days before that. You are more likely to get pregnant during the last three days of this time. Your body also gives you signs that you are ovulating. It estimates by counting 14 days back from the day you expect your next period. Or it occurs within 4 days before or after the midpoint of a woman’s menstrual cycle.

Quick Answers

How do we calculate fertile window?

Observe the length of your menstrual cycle which could range from 23-35 days. The length of your menstrual cycle is the number of days from the first day of your menstrual bleeding cycle to the first day of bleeding in the next month. Now, subtract 14 days from the end of your current cycle to know the approximate day of your ovulation. The best time to get pregnant is just one or two days before you ovulate. Otherwise, leave all this hassle and use our Ovulation Calculator.

How does fertile time help me?

Once you know your most fertile time, you can either avoid getting pregnant or plan for it. The ovulation calculator provides you with the exact time of your fertile window. The six days during this period are important in terms of pregnancy plans. If you have intercourse one or two days before ovulation, then there are high chances of you getting pregnant.

What fields do I need to enter?

You need to enter the first date of your last period. Then you have to enter your average cycle length. You will get to know those six days of your Fertile Window along with the day on which you will ovulate.

Do you ovulate just for one day?

Ovulation lasts only for a day. The egg starts its journey towards the uterus once it is ruptured and then stays viable for a day. Sperm can live in the uterus and the fallopian tubes for up to six days.
