Help

I am 36 years off age and I am having some health issues. I was diagnosed with Leukemia 6 years ago but I have been clear for 3 years. I still have a very severe blood disease (don't remember the name). My question is I have the mood swings, the night sweats, very emotional at times, I have not had a mentrual cycle for 2 years (and I have not taken or done anything to stop the monthly visits), and I am having stains (brown) in my underwear that will not come out. Could all this be the start of menopause?

Also the mentrual cycle thing my OB has put me on pills that was suppose to make me start but they never worked. And I have a huge lump on my right leg that I have went to over 20 speacialists for and noone can tell me what it is. All they say is that I will lose my legs because of the blood disease within 10 years.

Any answers would be greatly appreciated
