If you and your significant other are trying for a baby, this ovulation calculator can help. With a bit of data, you can find out when you’re most fertile, and when you will ovulate over the next three cycles. Try out this ovulation calculator to improve pregnancy chances and estimate due dates.
What is Ovulation?
Approximately two weeks before your period, your ovaries release an egg. The process happens in the middle of your menstrual cycle and is called ovulation. When you are ovulating, you are at your most fertile.
The most fertile period also begins a week before the day you ovulate, as sperm can survive in your body for a week. Your egg has a one-day lifespan, so your fertile window ends one day after ovulation.
The Principles of Ovulation Tracking
For the ovulation calculator to be helpful, it needs you to enter two pieces of information. You need to know the day your last period started and your cycle length. The typical cycle is 28 days, but it can be shorter or longer.
When Do I Ovulate?
Ovulation begins in the middle of your menstrual cycle. Usually, this is two weeks before your period. For precise ovulation times, you can check your cervical mucus or body temperature. Your fertile window is also one week before your ovulation, ending one day after it.
When you use our ovulation tracker, you can find out when you will be most fertile. Let’s say your last period arrived on October 14, with a 28-day cycle. Your fertility window would be from October 21 to October 29. Once you enter the correct information, you also get three periods of information.
Your Due Date When Using Our Free Ovulation Calculator
This free ovulation tracker is a valuable tool. You can learn what your most fertile time of the month will be for three cycles. It also shows you when you would be due if you were pregnant at that time.
A pregnancy lasts, on average, 280 days, or 40 weeks. Around five percent of women will give birth on their due date. The rest will be a bit earlier or later. If you conceived a baby from October 21 to October 29, your baby would be born around July 21.
