I am 48 years old and have not had a monthly cycle since December 2013. I have taken 3 home pregnancy tests which have all come up negative. Could I be in the beginning stages of menopause? I can only recall one or two days when I felt moody but when I got hold of myself rationalizing that this could be the case and I need to watch the way I react to things, I haven't had anymore trouble. No hot flashes, not trouble sleeping at night (actually, I'm exhausted it seems). I also crave things that aren't normal for me such as pomagranite juice, lots of milk, asparagus.... Any help here?
