I am 26 years old and I barely ever have a period. I havent had one since 1/2009. Last year I had a period that lasted 180 days strait. I had a few days in between that I didnt have it but mostly everyday. Now I did go to the doctor and they ran a bunch of tests but they say nothing is wrong with me. Do you have any idea what this could possibly be? Also if I dont have a period does that mean I do not ovulate. Thanks.
