I have had a previous miscarriage (Turners Syndrome) and I am now 7 weeks and 3 days pregnant for the second time. I have no children so I'm especially scared. I went in for my 7 week appointment and the baby's heart rate was only 109, but measured normally at 7 weeks. My doctor thinks I have a less than 50% shot at this pregnancy working out. Has anyone else experienced this? With my first miscarriage everything went perfectly until it wasn't at 10 weeks. My HCG was 83,944 (has been on the high side the whole time) and Progesterone is 33.2. I'm having such a hard time and don't go back for a week. Can someone share their experiences with something like this if they have one?
