Im 26 year old female this has been going on for over two years, blood tests, paps, ultra sounds, etc have all been completed numerous times and all come back with no answers. I bleed lightly anywhere from 5 to 3 days before my period and recently this month I finished my period a week ago and yesterday woke up with some cramping and light bleeding again (enough to have a pantie liner) still bleeding but the cramps lasted only that morning for about 2 or 3 hrs. I've been on birth control for several years, been off birth control and tried several others but the doctors still cant figure it out.... anyone have any ideas I can suggest for the doctor to look into that maybe more uncommon?? I have Thalassemia B trait if that would make a difference.
