Had neg test in the middle of a 3 day heavy & painful bleed, on sun. Bleed now stopped but I did positive test just now (3 days later). I know its possible that my hcg may not have fell since et on 20th & this is giving me the positive. But the neg test 3 days ago must mean hcg is rising, must'nt it? At what point of a failed pregnancy does hcg stop rising. I don't know what to think.
