I had an ultrasound at 6 weeks to determine my exact due date, since I have very long cycles. I was worried about going over 42 weeks, when I wasn't really overdue and risking out of my birth-center. I was thinking that that would be my only visual ultrasound. My MW used a Doppler twice to hear the heartbeat, so now I have had a total of 3 ultrasounds, if you count the Doppler. My MW will use a feta-scope from here on out, since I am 25 weeks and the heartbeat can now be heard clearly without the Doppler.
My husband and I are both really worried about the how the ultrasounds will affect the development of the fetus, and about the loud sound waves that our fetus would be exposed to. I opted out of the 20 week anatomy scan, but today I just started crying with worry, and am thinking about getting an ultrasound soon. I follow a gluten and dairy free diet (which would limit my folic acid sources a little), and threw up my prenatal every time I took it during the first trimester, because I was so sick that I couldn't drink water. I am worried about neural tube defects, because I had very little folic acid during this time. I am mainly worried about anencephaly, because my brother in law was just just diagnosed with the MTHFR gene mutation, which increases the risk for this anencephaly. My husband has not been tested for this gene mutation. I would really want to prepare myself emotionally for something like this, but I think I am just going crazy with hypothetical scenarios that probably are not the case.
Since I know there are a lot of well-educated Mommas out there, I was hoping someone could help me weight the pros and cons. I really wanted to limit ultrasounds, but this is really weighing on me emotionally. My husband feels very strongly that he does not want an additional ultrasound, but says he will support my decision in the end.
