Braxton Hicks?

M
31 & 4...Since this afternoon, I've had this constant pressure in my belly & below. It seems like Braxton Hicks to me, but it's been happening all day. My belly will get very tight & I feel pressure in my pubic bone area, & then it lets up & my belly is soft again. Over & over. Also, my belly just feels... Heavy. I can't really explain it any better than that.  I've read that having more than 4 Braxton Hicks contractions in an hour is a cause for concern, but I'm not one of those people that like to run to the doctor every time something seems off. I usually like to wait it out. Just wanted to get your opinions & see if any of you are maybe in the same boat? Thanks ladies!
