Ok so I'm 30 weeks pregnant and the baby is breech. What am I feeling?

Her head is right under my rib cage. For about the past week I've been having this feeling. It's kinda crampy around my rib cage and in the middle and lower part of my back... It comes and goes and when I have it it kinda feels like her head is pushing out of my stomach up by my ribs ( my stomach actually changes shape on the upper right side ) and then I get a horrible pain in my back. Almost as if she's trying to flip over by kicking off my back... Anyway, my question is this, is it possible that this is what I'm feeling or is it something else? Whats your opinion on this ladies?
