So, I plan to have one ultrasound done at about 20 weeks and, if all goes well, that will be it. I know some people have more and some people have less (which would be none). I'm curious as to why you, personally, choose the number of ultrasounds that you do?
I'll answer my own question...
I like to have one ultrasound because if there is something clear and/or seriously wrong with the baby, I want to know about it. Since I am planning a home birth, I especially want to know if there might be an obvious issue that would require extra care of the baby... like a heart or intestinal issue needing surgery. I also worry about where the placenta is and feel better knowing there's no reason to be concerned about that. Beyond those concerns, I do have concern about the risks of ultrasound and therefore avoid any further ultrasounds. I have consented to a BPP, which does involve an ultrasound, at 42 weeks with previous pregnancies.
I am always, however, eager to hear how others make such choices since I know that there may be things to consider that I have not thought of or that have come to light since I was last pregnant 5 years ago.
