Braxton hicks???

Hey y'all, I'm a first time mom, and I am 29 weeks+3 days and I was wondering if what I am feeling are Braxton hick contractions or not. I'll get a tight feeling in my stomach which makes it hard to breath, than it will let up. Than I'll also get pressure near my pelvic bone. They just started today and have only happened a few times. But I just want to know if that is what I am feeling or if he is just going crazy in there :)
