Growing pains or UC visit?

I'm in a lot of pain. Someone said it may be growing pains but this far into my pregnancy I've experienced the growing pains before- and they're normally just severe discomfort not this kind of stabbing my pain. It starts in my uterus and goes into my belly button and I'm feeling it up near my ribs. I'm not exactly sure what I should do because I am in a lot of pain and it is making me nervous. Do I go get seen just to put my mind at ease or should I try to see if it will pass?
