Rhesus-antibody in rhesus-plus pregnant woman?

[Mauricio Esguerra]

Dear immunlogists,

the doctor called yesterday to tell us that the antiboy E was found 
during the blood test of my pregnant woman (13. week). He is very puzzled 
since she is O+ and wants to repeat the test, since this can have seriou 
consequences to the bayb. We already have a kid, but lost "misteriously" 
the second half a year ago on the 7th. month. Is the presence of this 
antibody at all possible and could this be the explanation for the former 
loss? I would extremely appreciate your help on any information, although 
I am not a physician.
