Went to the scan, what a relief!!! It really was worth the peace of mind! I feel like I can relax and not be such a nutcase.
Baby is measuring 6w3d, the first heartbeat was 132, the second was 138. We saw the yolk sac, and the little bean. We also saw blood flowing to the heart (at least that is what she said it was). It was an abdominal ultrasound, and she found the baby almost immediately. My last menstrual cycle was Sept 12, and she put my due date at June 24th. Although I am technically 7 weeks (since LMP), she said it is of no concern that the baby is measuring 6 weeks.
I was feeling dense, and my husband had to remind me the 7 weeks was based on my period, and not on when the baby started to develop.
So yes, $75, and I do have another scan by the doctor on the 10th, but soooo worth alleviating the anxiety.
Also, she gave me a coupon for finding out the gender early and some 3d/4d stuff. I am still on the fence on whether or not I want to find out the gender (leaning on not) but the 3d sounds cool later in the pregnancy.
