Doing anything special? Multiple Miscarriages

Krista • My family consists of my husband, step-son, my son, our 3 cats and 2 dogs. We are TTC our first child together.
I have had 3 miscarriages and one healthy baby boy (2 angel baby's, my son, then 1 angel baby). My husband and I are trying to conceive again and my doctor says there is nothing really to do to help prevent a miscarriage. She offered to do regular blood tests after we get a BFP and to do early ultrasounds to help my state of mind so that's good.
My question for all of you is - are you doing anything to help prevent another one? Even if it is just something that helps you mentally.
