RH negative

Gesica
Any one here that has RH- ?
I got my BFP yesterday I'm a RH-, I had a miscarriage last year because of my blood type I had a shot of Rhophylac at the hospital to prevent that to happen again, but I'm super nervous that is going to happen. I don't know if I just go to the hospital and see a doctor there.
Have any of you gone through the same thing? What did you do?
Thanks in advance.
