Needing advice please.

I'm 33 weeks pregnant. I woke up with period-like constant pains at 1:45am it is now 3:10 am and I'm still having the constant pain. It's nothing excruciating, it feels like I'm on my period or something. I feel like I have slight pressure. I'm a ftm so I have no idea what to expect, and I don't want to be one of those that go into ER for every little thing, and I'm not in a lot of pain so is this normal? Or should I get this checked out?
