How to calculate ovulation period

A woman can determine her time of ovulation by some very simple methods. The simplest method is just a temperature chart. Before she gets out of bed each morning, she takes her temperature, writes it down on a chart. And at the time of ovulation, the temperature is at a baseline level, it's kind of consistently low until ovulation, and it shifts up and stays up after ovulation. That's probably the oldest method that was used for ovulation determination. Today we have some very simple, very direct, and very accurate means of determining ovulation. It's by doing a little urine dipstick. Women can check a urine sample starting on about day 10 or 11 if they have a 28 day cycle. And each day they do a little dipstick and there's either two lines or a smiley face that shows up the day that their LH surge occurs, that's the hormone that's released from their pituitary gland that precedes the release of the egg by about 24 hours. So if they test each day, the day that's it's positive that's when they have intercourse that day and the next day and they'll be hitting right at ovulation time for pregnancy occurrence.
