Anyone scared of labour

So me and my hubby are trying for #3 and I'm worried about labour pains. #1 was painful (obviously) but not horrendous, but #2 contractions were REALLY painful. I think its cos the body knows what it's doing, but now its making me worry about what it will be like for #3. I know it's a way off yet (but being as my period hasn't come and we've been TTC its brought it home) and now I'm worried about it :( x
