So I've been nleeding for around 3 weeks now. Started off like a regular period, and then when I thought it was subsiding....BAM.....2 and a half more weeks of heavy bleeding, huge clots, all bright red. Went to the doctor and had blood work and an ultrasound. Waiting for the results. So I'm on here to see if anyone else goes through this and if it might be Endo-related. The wierd thing was that I would wear a tampon at night along with a pad, and if I laid on my back I would get severe cramps, and would have to get up 3 or 4 times thoughout the night and when I stood up, it would literally "shoot" out of me. Even with the tampon. After morning came, after about an hour of standing up, my period would be extremly light thoughout the day and happen again and again every night. Wierd right? I understand the laws of gravity (obviously), and have had my period for 13 years, but not like this. Only when I laid on my back. Anyone else have imput??
