I wanted a water birth but after three days plus of contractions ramping up and dropping off I went in and begged for help. I was told I could have pethedine but that would mean no pool birth. So worth keeping in mind. My birth plan said pain relief as needed, nothing ruled out, but I still had to be very clear I wanted the pethedine, I think because the midwives wanted to give me the opportunity to have the birth in my birth plan, which I respect.
I took the pethedine, and slept for the first time in 72 hours, then got transferred to the consultant unit so they could break my waters. They offered me the epidural straight away, and I discussed it with my husband for a sec, and went for it. Best decision ever. I slept through the next six hours or so, and then dozed on and off for another couple of hours, I was exhausted when I got to the hospital but the epidural really saved me from running on empty when it came to the pushing stage.
Worth bearing in mind, you will have to have a catheter, however for me this was a huge relief as it turned out a blocked bladder was delaying my labour, once the catheter went in and they broke my waters I went into full labour very quickly. I also had a completely numb right leg for several hours after they took out the epidural, and in fact it was about 4 weeks till my leg was completely back to normal. That meant I had to stay in hospital an extra night, they didn't want to release me until I could get around safely. I would still have an epidural again, I had a very calm, peaceful labour, which is what I wanted with the birthing pool. This time it will be in my birth plan from the start.
