Scary stuff - I was induced with DD1 (sounds similiar to your #2) and it took me ages to recover BUT delivery with DD2 was amazing - complete opposite infact, I went into labour spontaneously, was gently active through most of my labour and arrived at the hospital at 10cm dilated. I had her 40 mins later (she was posterior too). No PPH and easy recovery. To be honest I was petrified of giving birth after DD1 (not sure how I only realised that at 30 weeks pg ). I spent considerable time physically active, so walked (perhaps waddled was a better description) for at least an hour every day and really worked on my own belief in my bodies ability to deliver as I really believe my brain stopped everything last time. Obviously every birth/person is different but believe in yourself and your body. Perhaps it is worth talking to a counseller about your concerns too. I was lucky enough to have an AMAZING midwife who really listened to me and made things feel so much less frightening. Start telling yourself you can do it! Good luck!
