2nd trimester miscarriage

About 3 weeks ago I suffered a miscarriage at my 19 week mark. We are absolutely devastated, but want to start trying again as soon as possible as it is very important for us to have our children be “close” in age. It took us almost 10 months to get pregnant and after losing our precious baby, we are terrified of how long it will take to conceive and if this same thing might happen all over again. The cause is suspected placental abruption. Not due however, to any trauma I physically experienced. HaS anyone else suffered through something similar?
