Or post partum haemorrhage. I ask out of interest - I had a planned CS a couple of years ago, which all went well and was a very comfortable and enjoyable experience for me.
I lost 1200 mls of blood, which I only know because the community MW commented when she looked through my notes. I remember them saying at the time that I had lost 'a bit' of blood, but I felt fine and my iron levels were very good, so it seemed to have no ill effect. I recovered well and fast after the op, Bf-ing was no problem.
At what point does a bleed become a PPH, and does it affect people differently? Obvs if I had been anaemic during pregnancy I can see it would have been a problem, for example.
