Supposed to be 8 weeks but measuring 6.

Samantha

I had my first appointment yesterday and should have been 8 weeks 3 days based on lmp, but baby was only measuring 6 weeks 1 day. I know when I ovulated and I got my first positive pregnancy test April 23rd so over a month ago, so it seems unlikely that I’m only 6 weeks along. Baby did have a heart beat of 167 and was high in the uterus. Anyone else experienced this? Should I be worried. I go back in two weeks to check growth and it’s driving me insane waiting.
