Yes u are more at risk with each pregnancy, but then again what kind of management did you require with the last births? My sister had small pph's with b2 and b3 and for her fourth we made sure she had synto and there were a few liters of fluids on hand for her. Yes she had another bleed, but it was well managed at home and she was fine.... I guess it all depends on what u have needed in the past as to whether there are further things you could do at home practically. Also on how far from hospital u were and what midwives were around...
