They ran so many tests on me. I am 41 and I stopped menustrating (thought it was stress due to son being killed in accident). My CBC was completely normal and so was thyroid and everything else they check to find out why I have not had a period and they determined I am in the early stages of menopause. What a shock that was to get that news because it does not run in my family. I still think it has to do with stress. Well anyways thanks for your reply to my post.
