Placenta Previa

Amanda is a 32-year-old female presenting with painless vaginal bleeding at 32 weeks gestation. I woke up around 5 this morning and my underwear and sheets were soaked with bright red blood. There was quite a lot - I would say it soaked through a thick pad in about an hour. The bleeding has slowed down a bit since I got here but it hasn't stopped completely. Your task is to take a focused history from this patient.
