i saw my baby around 7 weeks, and I didn't really see much, quite honestly. Thank goodness they point everything out! haha. I saw the gestational sac and whatnot, and the tiny tiny tiny cell-like thing that looked like my baby and a little heart flickering. I went back at around 10 weeks and OMG! What a difference. I couldn't believe it had grown that much! I saw the head, the arms, and tiny stubs for legs lol. It was gorgeous. He/She was dancing around for me in there too.
So that just goes to show how much difference a few weeks makes! I'm sure you'll be in awe of how much bigger it is next time you go. I'm very happy that everything is okay with you and your bubs

You'll be surprised how quickly time goes by and how they grow so rapidly!
