I would call and see what they say to do at least. They might have you stay home until your water breaks or they might have you come in to see if its the real deal, but you should just let them know so you know what to do!
I'm not sure if I'm being dramatic or if it's the real thing. I had an appointment yesterday and my OB said I wasn't dialated at all. That's why I'm confused. I have a pretty high pain tolerance so I'm not sure if this is what it really feels like.
You should call your doctor. Just from the contractions and pressure they will want you to come in, I'm almost 35 weeks and went in a couple days ago for the same reason but they stopped my contractions. Good luck and hope its time!
