All went well! I'm measuring at 7weeks, 5days. Due July 19th. Only a day off from what I had guessed, since I didn't know my LMP.
Little Blueberry's heartbeat was at 160 bpm (I guess this surprised me, I thought that was a little high.) He/she was hugging really snug to the uterine wall, but the tech wasn't worried about anything at all.
I'm so happy. Thanks for your good thoughts!
