I had a early scan 11th Feb as I bled on the 10th. I was told baby was measuring 4 weeks but no heartbeat. I knew my dates I was meant to be 7. I went home and naturally miscarried the majority on 14th. I had to go epu for bloods and scans. Latest being a week ago. I was told everything is looking as it should (in these circumstances). My blood level had gone down to 40. I was told to take another pregnancy test today and its faintly positive. I am just wondering how long it took for you to test negative on a pregnancy test after miscarriage?
