Update from last week

This is my first pregnancy. I'm 36. We have been trying for 3 years. We finally got our positive a few weeks ago. I posted last week that I had my first ultrasound and after the dr said everything looked good he became concerned after seeing the heartbeat was only at 93. I had my second ultrasound yesterday at 7 weeks and it was awful. The ultrasound tech didn't say anything to me and then I had to wait about an hour to see the dr to find out what was going on. Longest hour of my life. Well the dr told me that nothing changed from last week. There is still a heartbeat but everything is the same and that is all he could tell me. 3rd ultrasound will be next Monday. I don't know how to feel. Sorry so long I just need to vent. Thanks for reading.
