Breech babies

So my obgyn is not very helpful and isn't giving me much information about breech babies. I'm 32.5 weeks with baby #2 and my baby girl has been in Breech position throughout my entire pregnancy. I know she still has time to move but I just want to understand more about what they could do if she continues to be stubborn and doesn't move. I have an ultrasound in two weeks to determine her position. I'm also experiencing regular cramping and pressure and wondering if her position could be making it worse (my doctor is not concerned about this. I just want to understand). Has anyone been through this? Advice?
