On the other, it takes a remarkably long time to train as a physician. Some specialists can take 16 years or longer to complete their training, and even family practitioners -- who treat a wide variety of conditions for patients of all ages -- typically require a total of 11 years of schooling.
The fact of the matter is that, while you will only ovulate for about 24 hours, the period of time that you are actually fertile is more like 5 or 6 days. After sexual intercourse, once the sperm are in a womanâs body, they can survive for as many as five days afterwards.
Ovulation usually occurs between day 11 and day 21. Each woman ovulates on her own schedule. You've probably heard that ovulation occurs on Day 14 of your cycle, but that's not necessarily true. In fact, even women with 28-day menstrual cycles don't always ovulate on Day 14. One study found that fewer than 10 percent of women with 28-day cycles were ovulating on Day 14. Usually, when a woman says she is ovulating, she's referring to the especially fertile period of two to three days that precede ovulation.
