Of course, exactly when a woman ovulates isn't altogether clear. It all depends on the length of your menstrual cycle . If you have a 28-day cycle, which is the average, then you would ovulate halfway through your cycle. But if you have a 35-day cycle, you would ovulate around day 21 not day 17.

Some women are very aware of when they ovulate.
Other women don't notice any changes at all. If you're thinking about getting pregnant, try to track your cycle for a couple of months. You can get a good sense of your cycle if you chart your BBT for a few months. If you still have trouble pinpointing the exact date of ovulation, you might consider trying an ovulation predictor test . Add your comments to the bottom of this page.
