I just noticed you said "hopefully they'll LET me out of bed." The first thing you have to do if you want a good birth experience is let go of that thinking. YOU have to be in charge. Go against hospital policy, go against your doc, do what feels right to you. I can tell you right now, being stuck in a bed during labor is NOT going to help you at all to go without pain meds. Its amazing how much of a difference moving around makes. Even with a condition like preeclampsia, you can be up and moving as long as you keep your BP down (I'm not saying you have this, I'm saying I did and I was STILL up and moving, no way a normal pregnancy should mean you have to stay in bed.)
I had a terrible experience with my first so I tried to make it better with my 2nd. Here's what I did: I didnt get into a gown. Ever. Being in a gown makes you the patient-you arnt sick, you're having a baby. You shouldnt need a gown. I wore a dress to make checks easier and ended up completely naked at the end anyway. I didnt stay in bed. I bounced on a birth ball, walked around a little, went in the tub (which was against hospital policy btw), ate and drank my entire labor (also against hospital policy, but my midwife was with me on that....I'd bring my own snacks if yours isnt), didnt get an IV until I needed one (In my case, I was there because of preeclampsia and was being induced, when other methods didnt work, I agreed to pit, which is EVIL EVIL STUFFF!!!!). I also told the nurses to shut up when they were counting as I was pushing and telling me I wasnt doing it right...
I think I was about to smack one of them...who cares how I'm pushing, the baby was coming out
Another little piece of advice. If you water breaks and labor hasnt started, STAY HOME. If you head to the hospital, they will have you on pitocin before you know it and insist on a cesarean if you go 24 hours? I think. So stay home, do your normal routine, once labor really gets going go in and if they ask, say your water just broke before coming in. They'll still monitor you for signs of infection, but going without internal exams will GREATLY reduce the chances of getting one. Also, if you are having contractions, go in, and find out your not dilating, just go home. Dont stick around, because again, before you know it they'll be pushing pit.
I'm not trying to freak you out...I'm simply saying, you have to get to a point where you feel like you are the one in control. Otherwise, you will more likely than not be pushed into things you dont want and be one of those on here writing about your unhappy birth experience...and I'd hate to see that if it could be avoided!
