my experience was v positive, and i was like you before hand, very scared!
First off, i listened to natal hypnotherapy birth prep cd every day from 36 weeks and these helped me to feel more prepared and calm in those last few weeks. I would definitely recommend.
On the day before my due date my waters went at 4pm while i was sitting on the sofa. No dramatic gush, just a constant trickle over about half an hour.
Contractions started at about 5.30pm and just felt like mild back ache. Put tens machine on at about 6.30pm as i had heard someone say you should put it on early while contractions still mild, but i didn't feel like i needed it for pain relief at that point.
At 7.15pm we got into car to go to hospital as they had asked me to go in just to check me over as waters had gone. In the car i realised contractions had gone to every 3 minutes and were stronger but still very manageable. Got to hospital at 8pm and was sure that after the check up they would tell me to go home. Turns out i was already 4cm!
At about 10pm i asked for some gas and air as the contractions were coming about every minute, and at that point the midwife ran me a bath and put me in there with the portable g&a. The bath was bliss and honestly I felt so calm and happy. I just went with the flow and kept in mind that the peak of every contraction only lasted a few seconds and that my body was designed to handle it.
At 11pm I started to feel the need to moo and midwife said I should get out of the bath as I was ready to push. I was genuinely shocked as the pain was no where near as bad as I had imagined it would be at that point. I thought I was only about 6cm dilated.
It took me 45 mins to push DD out and it was hard work but not as painful as the labour part because i was concentrating so much on pushing. I didn't have any 'ring of fire' feeling as she came out and i only had a slight internal graze. She came at 11.49pm using just water and g&a for pain relief, 8 hours from waters breaking and just under 4 hours in active labour.
Even DP said that he was shocked at how easy it seemed. He says he kept waiting for labour to really kick in because he expected shouting and screaming like he had seen on 'One Born Every Minute', and he was really shocked when MW said it was time to push because he had expected me to be weeping and wailing by that point.
I felt brilliant straight after, and would do it all again in a heart beat. In fact, my only regret is that I can't remember some of the pushing stage because i was a bit out of it on g&a and i can't remember my DD actually being placed on my chest.
Your body was designed for this, just keep that thought in mind and you will be fine.
