First U/S yesterday - a little scared

beanbag2013

I had my first u/s yesterday. Everything went great. It was so amazing to see what the little baby looks like and to see the strong heartbeat. I thought I was 12 weeks, 3 days and the u/s tech told me the baby was "a little small". So I wasn't nervous when I left, but today I got an email from my doctor saying the baby measured 10.6 weeks which is much smaller than I expected. So now I'm nervous that the baby is measuring 2 weeks smaller than expected. FWIW, I am positive about my last period and get them fairly regularly.

Please tell me I'm worrying over nothing!
