Most shocking, my waters were actually quite mucous-like, not fluid-like as I thought it would be...
That I didn't care who saw me naked, very unlike me!
That my body would take over and I couldn't stop pushing when asked to - was offered an epidural and said "yes, please!" despite my needle phobia.
That I'd be allowed to push for so long and my resulting piles hurt worse than the stitches from the episiotomy and third degree tear I had. The stitches actually healed much quicker than the piles did!
That I'd be told I needed a blood transfusion three days after giving birth - I assumed I'd be told right away or at least within a day.
That breastfeeding would be so tricky! DS just wouldn't latch on properly, and was about to give up at 6 weeks and then it all suddenly came together. Subsequently, I got enough milk to feed two babies! Goes to show that sometimes if you keep at something, you can get good at it unexpectedly!
Really the most shocking was that despite having a fairly traumatic birth experience, it didn't put me off getting pregnant again, I recovered super quickly!
BTW, can't remember where I read this, but I think sometimes stitches are done right after birth without being numbed because we're meant to be numb down there after the birth for about 10 mins? I'm grateful I was numb from the boobs down from the spinal!
