i had a d&c; for a missed miscarriage sept 6. there was a large amount of tissue that they removed. they said if any was left behind my hcg would start rising again. lab results had my hcg at 301 on Sept 18 and down to 61 the following week (25th). they stopped doing bloodwork so I took it upon myself... clearly the line is getting darker.. we BD'd one time. i don't think it is a real pregnancy. wtf is happening
