My friend has a negative blood type and was sensitized on her last delivery because her midwife was dumb and didn't have her get the RHOGAM shot ever She is trying for another baby, and I *think* she met with a MFM to talk over the possibilities. She is a very optimistic person so she is taking it in stride, but I'm pretty intimidated by the thought of Rhesus disease, etc. Does anyone here have experience with this?
