I took 3 pregnancy tests last weekend and all came back positive. Mid week I started bleeding. I had blood work done and my hcg levels were low the first time and second time which was today they were still low. They should have tripled in the 3 days in between. I should have only been 4 weeks pregnant at the most. Would anyone care to share their stories with me if they have been able to conceive right after a miscarriage.?
