I had my first appt today. According to my LMP I am 7wk 4days today, but on ultrasound I measured 6 wk 1 day. I know a few days difference is to be expected if I’m not exactly sure when I ovulated, but 10 days worries me. She did see a heartbeat. She wants me to come back in a week to recheck but they didn’t have an appt open, so I go back on the 30th. She said we will just have to wait and see. I can tell she just didn’t want me to worry. Has anyone else measured this behind, or has in past pregnancies? Positive and negative stories both welcome, I can handle it. Thanks!
