please see my upload. I wasn't that worry but for some reason I have been thinking a lot lately. I have gone to the doctors several time and they just tell it's nothing and not to worry that it's probably nothing. I know that I'm not going threw pre-menopausel due to my blood results. I have been very tired all I want to do is sleep and been very weak also. I have had night sweats and very weak. I go to work and when I get home a will always have to take a nap. I have gone to the doctors and explained about my weakness and was told that it's probably due to all the bleeding. I have back pain I cant have intercourse due to pain also when I do I will bleed the next day. Also when I go to the bathroom to pee it has a very bad smell. Could this be cancer? Blood work was good that's what I was told. I have never use any protection during intercourse and doctors told me that I was probably not ovulating. I do have a lot of craps with sever pain and during my period. the pain sometimes is do intents that I wake during the night not being able to get up. Or I get you with bad craps that I only have time to go to the bedroom where I will start to bleed very heavily
