I had bright red blood yesterday when I peed and then for about 18 hrs after everytime was brown blood. Last 2 times there was such little amount I could hardly tell. I don't go for my ultrasound until Monday. I went to the hospital but all they could do was run bloodwork until the first of the week and my levels were quite low (170, at 3 weeks & 5 days). Can miscarriage bleeding stop and start? Or should I be in the clear? What's your experience?
