My doctor told me because I am RH-, if I start randomly bleeding. Then I need to come in and get my Rhogam shot ASAP. My last appointment was the actual time for it so I have had it now. But she told me that early on in my pregnancy. Hope this helps. You def. need to call your OB doctor and let them know whats going on!!!! I hope you get to feeling better!
You can receive the Rhogam after a miscarriage, yes. I would call the doctor and talk about it.
I think it is 72 Hours after the M/C.
Hope that helps!
