Brooke, I am so sorry for the loss of your precious Jed. Unfortunetly, I can understand a little of what you are feeling as I lost my daughter 18 months ago at 33 weeks. I cannot offer ant advise about placental abruptions however I had a c-section with my daughter and was told I could safely get pregnant after 6 months. I fell pregnant 5 months later and none of the Dr's or midwives were concerned about it. You have a long hard journey ahead of you, but it does get a little easier in time. You have definetly come to the right place for understanding and support, there is no way I could have gotten through the last 18 months and my last pregnancy without the amazing ladies here.
Take care
