I went to 9 cm dilated in the pool with only 2 paracetamol taken 4 hours previously, then DC got distressed so had to come out and get an epidural and emergency c section. I didn't even feel the epidural being done at the time as I was too worried about the baby.
Second DC and had another epidural and emergency c section, due to decreased fetal movement. This was discovered at a scan appointment, so I wasn't expecting it at all. Again my only thoughts were for baby's safety and did not realise epidural was done until they laid me flat again. I just sort of went on automatic pilot and did as I was asked.
Everyone's experience is different, and every pregnancy is different for every mother too, so it's impossible to say what will happen for you.
The best advice I can give is to aim for what type of birth you'd like, but be open minded to changes or advice from your midwife both before and during labour.
In the end, it's only the safety and health of mum and baby that is the most important, not whether you manage to get your 'ideal' birth, so try to relax as best you can.
It's definitely worth both the wait and the worry to have your DC in your arms. Best wishes to you and your little family. x
