I started having bleeding today after my fiance and I had sex, so I went to the ER. They said that there is a possibility of a threatened miscarriage. She checked my cervix and it was closed shut (which she said is a good thing). I am also having small clots and slight cramping. I had all of these same things happen in the beginning with my pregnancy with my son and everything turned out ok. My HCG levels were 734, and the doctor says thats low for 6 weeks. I have my first prenatal visit Tuesday and she told me to make sure they check them again and do an ultrasound. I might call my OB/GYN tomorrow and see if they can squeeze me in there schedule. I'm terrified that something is wrong!
