ladies help!

Cassie
hi ladies! ok I don't want this to sound sound dumb since this is my 3rd child but I have never experienced any of these things before. I am 38 weeks and 3 days and I went for a cervical sweep yesterday and I had a few painful contractions (I think) and was ok. now today I had sex (sorry tmi) with my other half and took a nap. well I woke up to back pain that's pretty constant and cramps in my stomach that come and go. I know yesterday I was 1 cm dialated...should I go to the hospital? I've had now 5 of these pains in about a half hr. please no rude comments I just need advice TIA
