Baby’s stomach measuring small

Hi,

Just wondering if anybody else has been in the same situation or if any nurses /ob’s are on here to get their opinion.

Went for my 3rd ultrasound to check growth on Tuesday. I am 38 wks tomorrow. They said baby’s stomach was small, checked my fluid, said they like to see at least a 5, mine was at a 7. Good , but low.

Now they are having me come in 2x a week to get an ultrasound , and the NST (non stress fetal test)

I am concerned with getting all these ultrasounds done. Is it really necessary just because her stomach was measuring small? I guess its hard to trust ppl sometimes wondering if they are just doing this for extra money?
