I genuinely wasn't scared. Maybe a bit apprehensive if I'm really honest, but not scared.
I was lucky enough to be low risk, no complications except low iron levels. I wanted a home birth and my iron levels after pills were just on the lower limit of what they'd 'allow' but they were good enough. I felt well educated, well informed and comfortable in my choices.
I went into labour at 40 + 5. It was very long- 36 hours start to finish (including a sweep at 21 odd hours in) and a good 10-12 hours of active labour, 3 hours of pushing (and nearly a whole hour for his head) but it was honestly fine! Really, really hard work and definitely painful but I never felt out of control, never felt like I couldn't do it and never needed more pain relief than gas and air. My 8lb 3 son was delivered at home in the pool. We actually ran out of gas and air at the end, but by that point it wasn't really doing anything anyway.
I had very minimal damage- 2 stitches for labial grazes that were stitched really just to be on the safe side and a tiny tear that didn't need stitching. He was born at just before 11pm and I was up making breakfast at 7am, and out taking the dog for a walk at 6pm the next day. I don't really mean that as a boast, just as an example that birth can honestly go like that.
Mine was not an 'easy birth' in terms of some women who feel little pain and who get their babies out with no effort, but it was amazing! It was definitely the most painful thing I've ever experienced but I just sort of got into the zone and didn't find it hard to deal with. I went from wanting one to instantly wanting another! 100% would do it again.
This is hard to explain in text so I really hope it comes across right but: I strongly feel like everything you do in labour can a positive effect on your birth experience, and anything that you can do to educate yourself will have some kind positive effect, even if it's just relieving any fear. Things can go wrong and there is certainly bad luck in labour, but anything negative that happens is not your fault. Does that make sense? You can't be in control of the bad things, but you can be in control of the good things! That kind of thinking really helped me. Hearing positive stories really helped me too.
