We went for my first ultrasound yesterday (thinking I'm 8 weeks) and didn't see a heartbeat. The doctor said I may have my dates wrong coz the yolk sack is small. She ordered another blood test to check if my hCg is increasing on Thursday and another US next week. She said a miscarriage is a possibility. I'm trying to stay positive during this time in limbo but it's tough. I'm hyperaware of my body for any sign of miscarriage. :-(
