Last Wednesday I had severe cramping and passed a large clot when I went to the bathroom (I was 6 weeks, 4 days). I went to the OB the next morning and they did a vaginal exam, said my cervix was open and confirmed it was a loss. I had my HCG done that day (12/19) then again on 12/21. My HCG has actually risen slightly. The OB's office called and I have to go in for an ultrasound but can't get in until Thursday because of Christmas. I guess I'm just wondering if anyone else has had a similar experience with your HCG rising after a loss.
