So had my first u/s today, I wasn't sure how far along I am since I had a miscarriage the previous cycle. I thought I might be 7.5 weeks, but everything measured 6.5 weeks which is fine. What's bugging me is the heart. We could see the heart flickering she showed us twice! but it wasn't strong enough to measure the heart rate.... sigh... hopefully it's just a little too early. With my DS he had a heart rate of 131 at 6w1day so I am a little worried. I know each pregnancy is different but.... sigh... I guess I'll go back next week for another u/s and hope all is good.
