I am going through a miscarriage. I'm about 95% sure. Been clotting for last 3 days. How long does it last? Anyone have this happen to them? I was 5 weeks. Ultrasound only picked up a sac. I'm waiting for my HCG test to come back...but given the amount of clots I'm having I know I'm miscarrying. How soon did everyone get pregnant after their miscarriage? This is my first Miscarriage. I have a 3.5 yr old and am 35. Got pregnant right away with both.
