I am 41 years old. I had my tubes tied in 1994 during a c-section. Around 2008 I had surgery because I bled for a about 5 weeks and I had a cyst on my right ovarie. I was fixing to get remarried and was looking into having my tubes fixed so of course I didn t want a partial or whole hysterectomy so the doctor left the cyst and just drained it. My periods are always on time. I may go down a few days the next month but I m never late with my period and as of today I m 16 days late. I ve felt exhausted for weeks to the point of can t keep my eyes open and I have had cramps and even back cramps that I never have. I ve been bloated and certain smells make me want to throw up. I have did 4 pregancy test which all say negative. I did a lot of reading on the internet and thought maybe my thyroid but I don t have all the symptoms. I ve had friends say it could be premenopausal but I m not having hot/cold flashes or anything like that. I don t know if menopause is a heredity thing but my mom had my 17 year old brother when she was 42 so maybe I just don t want to believe that s what it is. I know I need to go to a doctor but I really don t know what kind of doctor I need to go to and any suggestions on what could be wrong? Thank you, Becky
