Ultrasounds.

As of now I haven't had any ultrasounds, I'm 31 weeks and all they are doing is growth checkups. I have one ultrasound coming up do to the baby measuring big, they are checking her growth. Other than that, will I get anymore ultrasounds done before the baby is here? I really want to see what my baby looks like and how she is doing but I don't have money for an "out of the pocket" ultrasound. It has become frustrating to me. 😔😕
