Had the usual amount of ultrasounds with my first, who ended up cesarean. Had only 2 u/s the second time, once to establish pregnancy was not tubal, and once to adjust dates and find out gender, but then I walked out of the OB's office and hired a homebirth midwife at 30 weeks due to pressure she was suddenly giving me about interventions she had been fine with me not wanting, prior to that, and I had him at home.
Next child was also born at home, and had no ultrasounds at all. He had a true knot in the cord, which is or is not an obstetric emergency depending on whom you ask, but I would still have wanted to birth naturally and at home if I had known about the knot, and all having an u/s would have done, had it revealed that, would have been to make me nervous and give me more what-if mentality than is healthy.
This time, I still don't plan on having any medically unnecessary ultrasounds.
Of course, I'd do it if I needed to rule out placenta previa in later pregnancy (in early pregnancy, what seems like previa, will change as the pregnancy progresses, so no sense in checking for it early) due to a midwife's concern on feeling or hearing something that would prompt her to ask about an ultrasound, but not otherwise. <3 to you!
I edited this to make it a lot shorter, and because I was all over the place Off Topic due to hormones and the need to ramble.
