hi found this piece of info p[lease follow it. if you're rh-negative and you've been pregnant before but didn't get this shot another routine prenatal blood test will tell you whether you already have the antibodies that attack rh-positive blood. (you could have them even if you miscarried the baby had an abortion or had an ectopic pregnancy. ) do hope this helps and eases your mind. good luck
i had a miscarriage and didn't get rh- shot and now i'm pregnant again? will i have another miscarriage again
