I had a d&c on May 1st. I was 8 weeks 5 days pregnant. I had a missed miscarriage. I had a huge blood clot. So I have been trying to track of my HCG is out of my system. My doctor says it should be 0. She is going to do a blood test. I took a digital first response today and it is positive. I know I can't be pregnant. I also took a ovulation test and that is positive as well. I did have sex 2 time in the last 12 days. The first was 2 days after my d&c and the last time was 2 days ago. Anyone been in this situation before?
