DH and I would like to try for one more child, so if my little one is born Rh+ I will have no issues with getting the shot postpartum. He is very supportive about the whole thing, but I think would prefer if I just got the shot "just in case." My issue is that it seems like getting the 28 week shot would definitely negatively impact my baby, and all for a bunch of ifs. IF she's Rh+ and IF I have some kind of unlikely blood exchange with her and IF I am even able to get pregnant again in the future (we struggled with infertility for 3 years before gettingbpregnant due to my PCOS and his male factor issues.)
There is a knee-jerk frightened part of me that just wants to get the shot because all the studies say its relatively harmless and I'm terrified I would say no and end up having problems with future pregnancies. I cannot reconcile that part with the bigger part of me that is antivax, anti-medical fearmongering.
Plus, the 28 week mark just seems so utterly arbitrary. If I have a definite trauma issue, they would recommend another shot then anyway. I don't really understand the whole passive immunity claim, or why it magically lasts 12 weeks.
Sorry this is so long, but it has been preoccupying me a lot lately. Anyone have any experience/advice/info?
