Hi I hope my story can give you a positive outlook!
I had a pph of 3l with my DD, lost consciousness, blood transfusion, stay in hospital of a week, all pretty scary (particularly for my OH, as I was pretty much none the wiser during the worst moments!)
When I fell pregnant again (5 years later, think my OH and I were a bit scarred by the whole experience!!)
I was under consultant care, they said the risks were slightly higher but that they'd look after me and keep a close eye. Apparently the risk of a pph are much greater with a c section, so although we first thought otherwise and I might be advised a section, we went for another vaginal birth.
Well the midwifes were fantastic, in the end, DS arrived rather quickly, she was trying to get the cannula in my hand as he was coming out! They have me oxytocin as soon as he was born, I had a managed 3rd stage and all in all lost only 500ml of blood.
She was very attentive, kept asking me how I felt and checking my pad.
It was such a lovely experience to be cuddling my newborn, conscious and focused on him rather than the chaos that ensued with DD.
So anyway sorry for the rambling on, just wanted to let you know that it can be a very different experience even if you had a pph last time.
Wishing you all the very best
