Hormone imbalance

I am not sure what topic to add this in, but I am curious to see the answers..
Does anyone or has anyone had a really bad hormone imbalance (that causes various symptoms) and gotten pregnant and have it go away?
I know that happens to my cousin, and actually when I was 16 (now 21) I had my GYNO tell me getting pregnant would fix it. I'm curious to see if it actually happens!!
