pregnant after placental abruption

Chellsey
So I had a placental abruption at 37 weeks 4days with my first son , 9 months ago .thank god we were both okay and came through  I'm pregnant again which wasn't quite in the plan just yet and I'm terrified . My son and I almost died from blood loss and it was the most terrifying delivery of my life . I'm 7 weeks pregnant again and so far so good . But everything was perfect with my son till that day then my placenta detached 70% and fully abrupted when they checked to see if I had dialated  .with no reason as to why .... has anyone else had a placental abruption and gone on to have a healthy baby/ pregnancy  ? Back to back - at that .
