thanks for all the info and experiences ladies, you have definately put my mind at ease. i know mil is rh- so theres a possibility dh is too, he was supposed to find out for me and forgot to get them to do blood grouping on his bt, so he'll be going back lol. it matters for dcc as the hospitals policy is no dcc for rh- and i am planning on putting some strong arguments to my cause through this pregnancy, will help if he is - too.
But for now all i was worried about was the chance that my body would register this baby earlier and attack, i should know better than to google these things by now...
thanks kelly for all the info on this site and the fb dcc page as thats where a lot of my arguements will be coming from for the hospital.

thanks again girls, i feel soooo much better now
