Know When You Are Fertile?
The notion that your fertile time is between days 10 and 17 may
not be reliable. A study conducted by researchers at the National
Institute of Environmental Health Sciences showed that late ovulation
was common and that women can be fertile on almost any given day
of the menstrual cycle. This is important to know when you're trying
to avoid pregnancy. And when you're trying to become pregnant, it's
worth giving any day a try.
