During my first pregnancy in 2008, I wanted to begin with midwifery care right away, but my husband had many concerns to work through, so our first several appointments were at an OB's office that I chose because they'd been consistently reviewed as some of the best in Berkeley. Our very first appointment around 6 weeks was, I thought, to confirm the pregnancy, so I was expecting some bloodwork. Imagine my surprise and discomfort when the NP prepped me for a routine transvaginal ultrasound!
I wish I'd simply refused. We went through with it, the NP frowned at the screen, and told me that the fetal pole she saw was not developed enough for my dates, and told us to expect a miscarriage. She was not at all interested that my cycles were very long and irregular, and simply kept counseling us to prepare for the "likelihood" that the pregnancy was not viable.
She was wrong (because hello, she didn't listen to the patient!!), and our healthy son was born after a totally unremarkable pregnancy. So, after that totally needless experience, I opted to skip the dating ultrasound for my second pregnancy... which, naturally, led to a bunch of second-guessing and concern because I wasn't at all sure of my dates that time around!
So, this time, we did opt for a dating ultrasound, just to be totally sure we were where we thought we were. Now that we've done that, though, we don't plan for any more until the 20-week anatomy scan, and then--assuming smooth sailing--we're done.
