It's a good idea to get the rhogam shot after a miscarriage, too, as blood
can mix there and cause problems
but if you are pregnant again and so far no problems
, then blood type should not be a problem.
I also had to get the shot this time even though my husband is also -, just to be safe. Try not to worry about it, Rh- women have Rh+ babies safely all the time. Even in countries that don't give the rhogam shot like we do in the US.
