I am not going to tell you not to be scared... because it is scary! It's the unknown! If it was fun they would call it a party instead of labor! :)
Really the simplest things to do is try anything you can think of during labor and if it doesn't work then move on to the next.
I found a cold compress on my forehead, warm blankets on my midsection, massaging my hips, and deep breathing made the experience a lot more tolerable. I also had contractions in my upper legs (Did not expect that!) so anything sitting didn't feel good but laying down or standing felt very good to me.
Plus... if you feel you need it then allow yourself to get pain meds - but only if YOU want them and you are comfortable with getting them. I got the injectables twice and it really helped me relax since I had been awake for about 32 hours at that point. I even dozed off between contractions. I also got the epidural which was great (I took a nap - at that point it had been 36 hours of being awake and 20 hours of labor) until it failed... but don't be frightened by my experience with it. Would I do it again? The injectables - yes because it was a positive experience. The epidural? No... in fact when I do become pregnant again we will look for a midwife that will do a VBAC homebirth.
Good luck and have a happy and healthy pregnancy and delivery!
