Ovulation: Ovulation occurs in normal hormonal circumstances almost always 14 days prior to the onset of a menstrual period. On a "regular" cycle of 31 days, ovulation will occur on day 17. You can demonstrate this by buying a thermometer at a drugstore which measures degrees in tenths. Follow directions on the package, and a rise in temperature will tell you one day prior to release of an egg.

Ovulation: Ovulation is usually just shy of halfway through your cycle. So Day 15 to 17. Many women learn to feel the ovary release the egg. This is called Mittelshmerz. But, if you are trying to get pregnant remember that you will have more success if the sperm is there ready to meet the egg. Thus sperm on days 12 to 17 are the sperm likely to cause pregnancy.

July 24: If July 7 was the FIRST day of your last period, 1. Determine when your NEXT period will start by counting 31 days from the first day of your last period, then 2. Count back 14 days
