Thanks to everyone who commented, and so quickly! It was nice to have some affirmation that I probably can trust my intuition. It was also nice to get to the hospital and out in under an hour, be told the test came back negative (as in pre-term labor won't happen in the next 2 weeks), and kind of stand up to the resident OB and say look, 3 internal exams in 3 days just isn't necessary. All I got was an IV of fluids and some monitoring. Yes, I'm having contractions every 3-5 minutes, but they're not that bad, and since I've been having them for a while now they agreed not to give me any drugs (or steroid shots for the kid). That part was nice, I did feel I was listened to...and I'm sure men can make good OB's, but honestly, even I didn't really know what a cervix was until it got kicked regularly, how can they REALLY know what is normal or not?
Anyway, I go back to the regular doctor Monday morning (which is a real pain in the ass with teaching...I can probably get coverage for the period or 2 I will miss without having to officially call in sick, but if this is going to become regular he just will have to wait until 2:30pm to see me). I think I will have at least weekly, maybe twice weekly monitoring...which I really hope doesn't involve internal checks every time. Quite frankly, if you want the thing to stay closed, QUIT POKING AT IT! Geez.
I think I'm going to try some gentle swimming (I don't know any other way to swim without drowning anyway) and maybe yoga or at least some stretching on my own so that I don't go crazy. Not moving doesn't feel right. No running or anything, but maybe some water running.
