Ooh, that sounds awful, lela. Much, much worse than labour and birth to me!
Like getdown says, it sort of builds, and you get used to it - it's like bad period aches, but also because they come in waves you get a breather. They make you want to make odd moo noises, and I had a urge to stick my head into dh's stomach (he was standing in front of me).
Things which help:
I quite liked TENS machine in first labour - didn't bother with ds, though. I found it a nice buzzy feeling. You can hire them in Boots.
A gym ball in the early stages (but also v good for just sitting on in late pg) - I found lightly bouncing on it nice during contractions. You can get them in Argos - would recommend you get or borrow an electric pump if you do get one, though. the baby would be born before you'd have inflated it with a bike pump.
Gas and air is your friend. It's like instant, pleasant drunkness, but the woozy feeling wears off instantly when you breathe air, so you don't lose control.
Warm water is great. I'd have liked to labour in water, but for various reasons it didn't happen. I did have baths with dd and ds in early labour, and that really helped.
Moving around and changing position also good - you kind of need to do what your body tells you.
I had morphine twice. Once when delivering dd1, where I had it twice, as it didn't matter to poor wee dd1. It was v good pain relief, though made me a bit strange - mid-contraction, I had a terrible desire to know the name of the youngest child in Malcolm in the Middle. Fortunately DH had the prescence of mind to know and just answer!
Had it early on with dd, and it did help - should tell you that I ended up having her without anything, even G&A, because I wasn't really focussing by that point, and consultant took it away! I had a really good and trusting relationship with him, so though I shouted at him, it wasn't stressful, and for me it was right. It was sore, but never impossible. And she was huge.
With ds I had bath, then G&A throughout, and it was fine.
Just to reiterate - labour pain is a slow build, and comes in waves which give you a chance to recover and prepare. It's nothing like what your injections felt like - if you can come through that, then you can definitely cope with labour and childbirth.
Finally - lela- this is your thread. We can talk about childbirth as you want us to - this is about all the support that you need, so just ask away for what you need.
