Hi, My periods have always been 7 days long ever since I was 13, the first 4 days we're heavy flow and the last 2 or 3 would be light. I was active a few months ago With Protection. It's been 3 months since Intercourse yet for the past 4 months my period lasted 2 to 3 days and it's light. And my last one only lasted one day . I took a urine pregnancy test when I was active due to my period but it was negative . I have No type of Pain, is just bloated but yet no matter what I do my stomach doesn't go back to normal. I workout a lot, and I'm losing even more weight yet my lower abdomen doesn't go back in.. I have No pregnancy symptoms therefor I doubt I am and yet I have no pain so I feel it's nothing bad but I don't understand? Could you list what could it probably be?
