Jakana sometimes women hamorhage after birth. It is FAR more common when there has been intervention, but it happens where there has been none too. Previous complications and later pregnancies (3rd and more) can raise the risk, but don't necessarily. In cases like your sister it is difficult to predict and rare. I'm sorry it happened to her To minimise your risk of the same thing happening one can decline the use of induction drugs and stay upright and active to minimise the risk of forceps or ventouse being needed, ask for the cord to be left to stop pulsing after the birth and not cut until the placnta is delivered, allow no-one to touch or tug on the cord or push your belly and generally let nature do it her way.

When i gave birth i was about 10 minutes by car from hospital (40 in heavy traffic, 4 in helicopter which was a possibility as there is an air ambulance from there). I'm in the UK so you get a midwife no matter how far from hossie you are. My midwives had pitocin (to make my uterus contract hard, enough for 3 times the dose they use for the 3rd stage), adrenalin and oxygen with them as well as an IV shunt and 1l of fluids (saline). So if i had had a bleed after birth, they had equipment to keep me alive and my blood pressure above a dangerous level long enough to get me to hospital. You can ask what provision miwives have for this circumstance when you're looking to book one.

Another thing i would say is that LOTS of women are told "If you'd been anywhere else you'd have died" - i even know women who had botched inductions ending in c-sections told that - if they'd been elsewher they'd have died! What like, on the sofa waiting for bubs rather than hooked up to a drip at risk of infection after an AROM! Bleeds can happen VERY fast but midwives don't just sit there and watch, they IMMEDIATELY begin to stabilise you and stop the bleeding while simultaneously getting you to hospital as fast as possible. Because of the intervention statistically you're more LIKELY to suffer a PP bleed in hospital (which i know isn't much help when your sister had one with no intervention).
