Ovulation and Due Date Calculator
The best or most fertile time to get pregnant is the period of ovulation in your menstrual cycle. One simple way to know this is figuring out the starting date of your next menstrual period. From this date, count back 12 to 16 days. This will give you a range of days when you will probably be ovulating.
Cycle day one is what we call the first day of menstruation. In order to calculate the length of the menstrual cycle, you need to count the number of days between cycle day one and the beginning of the next period. At some point during the menstrual cycle, the ovary will release an egg, which signals ovulation for the woman. The egg that is released will make it way down the fallopian tube so that it can be fertilized by a sperm cell.
Since every female body is different, there is no equation that can be used to calculate the exact moment of ovulation. General rule of thumb states that ovulation usually occurs two weeks before menstruation. Therefore, a woman with a regular 28-day cycle will most likely begin to ovulate on day 14. A 32-day cycle will result in ovulation starting on day 18.
