... I was extremely healthy before and during my pregnancy and had one shot of RhoGAM during pregnancy and one shot of RhoGAM after delivery. My child is now 8.5 months and it seems as though my immune system is completely shot. I seem to catch everything and anything I'm close to despite all the hand washing and vitamin taking and it seems to take a whole lot longer for me to get over an illness than before I was pregnant. I was 31 when I had my baby, should my immune system be this bad eight months after labor? Is RhoGAM the cause?
