Yay!!! So happy for you. Your story reminds me so much of mine. I got blood tests, was charting, everything was fine with my first pregnancy. One day (I think I was around 8 weeks), I got a call from the Dr saying I was miscarrying and didn't I have any blood yet?
They booked me for a D&C the next day. My DH and I almost got into a car accident because we were so upset. Anyway, showed up at the Dr office, start the internal scan, and the lady was like "why are you here again?" I told her the Dr said our baby had died and I was there for a D&C, and she said, "well, I can see the heart beating right there."
Turns out they mixed my bloodwork up with another ladies, and I never was miscarrying. The Dr never saw it before. The only thing that really saved me was that I was still charting and my temperatures had never gone down. My daughter is now 6.
This is my third pregnancy now, and I haven't gone for bloodwork or appt. yet. I'm 6 weeks+ now, but I've been down this road and provided everything goes well, I'll go in closer to 10-11 weeks when they can possibly hear the heartbeat, etc. While I trust Dr's, my story really made me trust myself, too.
