Hello Aussie_Chik!

I also have rhesus negative blood so I have done a fair bit of reading on it. If you have had a previous miscarriage, termination or bleeding in pregnancy, this all presents an opportunity for antibodies to form, so in each instance, you need an anti-d injection for all of these things too.

I have never had any problems with positive antibodies coming up after my two births, but maybe it did happen and I just wasn't informed as it was deemed normal.

Sorry I can't be of much help but hopefully it is just related to the injections. Let us know how you go!
