Sorry to hear that you miscarried!
When I got my miscarriage I didn't know I was a Rh factor until they tested my blood. My husband is + and I am - so with my daughter I got the shot in the middle of my pregnancy but after she was born I didn't have to get it because she was - but when I had my boys I got the shot in the middle of the pregnancy and afterwards because they were +. It is not a big deal anymore! Good Luck! I hope this helped.
