I miscarried June 23rd 2017 (12 weeks) as we found out baby stopped developing and heartbeat stopped at 8 weeks. This was almost 7 weeks ago, I've had no cramps, no bleeding, no period, no pains of any sort so out of curiosity done one clear blue digital 2 days ago getting positive 1-2 weeks and again this morning getting positive 2-3 weeks, would this be a new pregnancy or hormones from the miscarriage, any advice?
