The problem is when an Rh - mother is carrying an Rh + child. If your Rh is positive than it's not a problem, however, if you're DH is negative and/or the donor is negative, you're child can be negative. If you have a daughter with Rh- and she marries a man with Rh+ and conceives an Rh+ baby, she'll have the following issues arise when she has a child---

The babies Rh + can cross the placenta during certain times like birth, during aminos, etc. The mother's body sees the Rh+ as being a foreign body (like bacteria) so it sends out the troops (white blood cells) to fight off the invader which causes an antigen-antibody reaction. When this happens, they also reach the baby. It's the baby that is at risk. It causes Erythroblastosis Fetalis which is destruction of the red blood cells in the fetus/infant. It's treated by giving Rh- blood transfusion to the baby to stop the destruction then gradually replacing the babies blood back into the baby.

This isn't so much a problem during a 1st pregnancy. Treatment is giving RHOGAM (a shot)within 72 hrs from birth or after an amino, etc.

During a 2nd pregnancy or other following pregnancies, RHOGAM is giving at 28 wks of pregnancy and again within 72 hrs from birth or at the time of an amino, etc.

So, I had a previous pregnancy many years ago w dh. I'm RH+ and we didn't have to get shots so he must be RH + too, right? ( can't remember what he was). Thanks so very much again for this info. Not sure what donor is though... But 2 RH+ probably cannot make a RH- right? Hoping she's RH+....
