I just came back from my first ultrasound, I posted that I was nervous because I am so early. Well! It turns out I am even earlier than I thought! I lost about a week of progress that I thought I had. The doctor said I am "barely 4 weeks". Anyway, I am happy to have been checked out and I could see the little tiny dot on the screen!
I got back in 3 weeks to, God willing, hear the heartbeat.
