I have not had my period for 4 months and I am not pregnant because a blood test was taken. Any ideas?

Don't panic, that is common. The same thing happened to my cousin and on top of that a doctor told her that she couldn't have any kids. Well she had an ultra sound and confirmed that she was 6 weeks pregnant. However you might have a cyst on you ovaries which is also common because I skipped a period before and that's when they discovered I had cysts on mine. They put me on the pill to regulate my period. Good luck

You need to see a doctor.I had this problem and then excessive bleeding due to thyroid disease.
It is never wise to try to self-diagnose,I know we all do it but your best bet is your gynecologist.

You need to go to the gyno, get a pap. Tell them what's the matter and asked to me check for everything!

Menopause? If your to young then maybe something is making you go through it early

I'm wondering the same thing. How old are you?

I am 31 now, but this happened when I was 23. It's always good to get it checked out. I am sure you will be fine.
