One of those days

So my doctor is starting to find things and today he mentioned PCOS as a possibility as to why I lost my two children. After reading up on it part of me almost feels like I am responsible for my children's death. My body was clotting up so the placenta couldn't feed my baby. My body was killing my baby... how can that be? My husband is perfectly fine... it is all me. It is all my body and all my fault.
