Ladies. This was my first pregnancy. I conceived easily. I was guarding myself until the first ultrasound at 8 weeks. The ob gyn told me with joy that the baby is measuring 8 weeks 5 days and the heartbeat was good and fast at 177 (if it's in the high 100s, she said that's an excellent sign). She told me the chance of miscarriage at that point is 0,5 percent (one in 200). I then relaxed a bit, told friends and family, and felt happy.
