I had a miscarriage in 2011 and i think it was due to my doctors mistake.

It was my first pregnancy, and i was unaware of the fact that if the mother has an negitive blood type and the father has a positve blood type, theres a chance the baby could have a positive blood type. if the baby dose then the mothers body builds up antibodies witch can harm the baby. the doctor is suppose to run lab test to determine if the mothers body is building up antibodies witch would indicate an attack on the baby. if this happens then the doctor gives them an rh shot to stop it. i went in for my first prinatal visit in january an was never told any info about this. them i went back for my second visit at 3months and was told the fetus had died. i believe this was from the doctors mistake and was woundering if i have a case.
