I went to the ER about this situation finally. Had blood drawn, and ultra sound they said everything came back ok, but I'm really scared since the ultra sound I'm passing blood clots more than before like every 30 minutes and they are always very VERY big. They said I'm alright but I feel otherwise I understand it's normal to have blood clots, but I went 3 months without a period and now I've had it for 4 months. I'm afraid I'm losing too much blood.
