Okay, I apologize in advance for how long this is, but I had a D&C over 8 weeks ago, after having an incomplete miscarriage

and my HPTs are still showing up positive. I went to the DR on Wed to get my blood drawn to see what my HCG is at, and that was negative for HCG, but my HPTs are STILL all positive! (And I'm using FRER tests, not cheapies) Has anyone had this happen after a miscarriage or D&C? We desperately want to start trying again but my body doesn't seem to be cooperating. When did your levels return to normal?
