Bleeding for 75 days

Sara

I miscarried on April 19th and have been bleeding every day since. I have gone to two different doctors and got two different ultrasounds that both showed no retained tissue. My last hCG reading was 10 days ago and it was at 1. Does anyone know what might be going on? I don’t think I’ve ovulated during that time but if I do I’m scared I won’t be able to conceive. I will take any advice!
