Narrow pelvic bone and BIG headed baby

At my 36 week scan my baby's head was measuring at 39 almost 40 weeks. Yesterday at my ogbyn appointment he checked my cervix and told me I had a narrow pelvic bone and we are going to do another scan at 38 weeks and if her head is too big, he wants to consider inducing early or even a csection because her risks of getting stuck or hurt are higher.

Has ANYONE gone through anything like this?

I know pelvic bones will loosen up and everything, but if my doctor has a concern I'm going to listen to him. Thank you.
