About 4 weeks ago I had a miscarriage at 5 weeks, I had a blood test and they said my hcg levels were at 29 and I had been bleeding for 8 days and clotting, I never went back for a second blood test as I just thought that was it for me, today now I took a test just to be sure and I had strong positive on a clear blue, I’m so confused could I have not misscarried ? Is a it a new pregnancy, I have to wait a week to have a scan should I book a private one to put my mind at rest????
