Sorry, thought I posted last night but I don't see my post here, so here goes again.
DS1 I had a postpartum hemmorage - blood loss estimated at 800cc (though I actually think it may have been a lot more, I didn't let them know fully, I don't think, how massively I continued to bleed postpartum because I assumed it was normal), midwife (the most senior one at the birth center) had to use hard massage, shots of pitocin, methergine (spelling?) until the bleeding slowed, and then a pitocin iv drip. It was a very bloody birth all around. Turns out I had a partial placental abruption. I had a totally (till the stuff to stop the bleeding) intervention-free, very fast labor - 2 hours 15 minutes from first contraction to baby.
I was really scared of pph the next time around, but everything turned out just fine. 8 pound 11 oz DS2 was born in 57 minutes (from first contraction to baby), but no hemmorage at all. Very little bleeding, actually, including postpartum.
First DS was born in hospital with birth center midwife. Due to bleeding when my water broke and overcrowding issues, I ended up at the hospital instead of the birth center, which was just as well. I would have been transferred anyway after the birth because of the bleeding.
DS2 was born at the birth center three minutes after we got there
Hope this helps, and good luck to you!
