I was thinking about how I seem to usually ovulate on CD12 and how my friend's doctor told her that women ovulate on CD15 so that is when she should plan to BD. Good thing I didn't listen to that advice or I wouldn't have my DS! Obviously I know that isn't true that all women ovulate on CD 15 but I was curious to know if it was even true that MOST women ovulate then. I think CD 12 is probably on the early end?
