Prepare for a long reply
After seeing the consultant my options were limited to patient controlled analgesia during labour and ga if c-section was required. The pushing stage was limited to 30 mins. The advice was that the chance of complications happening with epidural were small but the consequences were too significant to risk it. I was terrified after that meeting, and wished that I never asked the midwife the question. Again, I should say I was asymptotic.
As for the labour. For ds1 from start to finish it was about 12 hrs, 7 at home and 5 in hospital. The midwife wasn't aware of ac malformation, as my gp midwife had reassured me that it wasn't an issue. I pushed for 2+ hrs (hated that bit). In the end I used gas and air (didn't seem to help) but ds1 just wouldn't get in position so it ended in a ventouse delivery with a pudendal block. The pudendal is something I hadn't heard of it, but it offered so much relief.
Second labour, 10 hrs total 5 at home 5 at hospital. Again I used gas and air (worked amazing), after 40 mins of pushing ds2 wasn't for appearing so ended in ventouse with pudendal. This time the pudendal didn't help with pain. I think in my first labour the relief was largely psychological.
Speaking with the midwife after, she felt that during contractions I was almost keeping the baby in rather than pushing. In both cases I never got the urge to push, but I wonder now if that's because I had a fear of the consequences and so held myself back. I have to say, during the second labour I was relieved in the knowledge I wouldn't be pushing for hours and I knew (or had already decided) that it would be a ventouse delivery.
Speak to your midwife, consultant, etc and know your options. I was really upset that I couldn't use the birth centre, and that my options were limited given I had no symptoms. I completely understand your feelings about the ga. I was reassured to know baby would go straight to my husband in another room, it wouldn't impact b'feeding and I would come round immediately after birth.
I'd be really interested to hear the advise you're given! If you have any other q's please feel free to ask.
