Thursday, I took a blood test and it showed I was 3 weeks pregnant. My hCG level was 49. Tuesday, I go to the OBGYN and my levels dropped to 15. The nurse says my pregnancy doesn't look promising. I'm scared. Before I had the first test, my breasts were very sensitive and I was having sharp pains. Now, I'm bleeding, not real bad...but still. And, I had very tiny blood clots. What is going on? Why would my hCG drop that low that fast? Am I having a miscarriage? I'm very distraught.
