My doc is unconcerned too and just mentioned how rarely one near the cervix can grow in such a way that it blocks the cervix prohibiting vaginal birth. Mine are small though so she didn't think there was any chance of it happening since it is rare to begin with.
It still miffs me though

So far my mom, an aunt and a cousin have all had hysterectomies from fibroid issues, and I am so not looking forward to that if it becomes a problem with me in the future. I was hoping since I had to deal with infertility, I could avoid all that! Poo!
