Additional Ultrasounds for IVF Pregnancy

For those of you who have gone through an IVF pregnancy or are going through an IVF pregnancy and are in your second trimester or later:

Are you having additional ultrasounds done besides your second trimester ultrasound (specifically a fetal assessment ultrasound and an Echo ultrasound)?

My obgyn scheduled these two ultrasounds for me and said it was important to do because I am an ivf pregnancy which is higher risk.

I am just a little hesitant because I feel like I have already had quite a few ultrasounds during this pregnancy due to ivf (I’ve already had 4 and I am only 17 weeks along), and I’ve read that too many ultrasounds may not be the best thing for your baby.

Any insight you can provide, would be greatly appreciated!
