Period like cramps at 30+2 weeks

So I didn't have BH with my first child. Everything I've read described them as a tightening in the stomach. To me it feels like I'm about to start my period but a little more painful with some back pain. It's been like that a couple days but not consistent. I'm even having dreams every night that my baby came early. I'm sure it's just normal pregnancy pains but the dreams are freaking me out lol. Is it worth going in for? I would have just gone already but it's not very close and don't have the money to spend on gas this week.
