Hi i've found the thread. Here it is:

Rhesus D negative blood group

The other ladies pretty much said it to a Tee, so I don't really have anything to add other than, I am pregnant with my second baby, and it really is nothing to worry about unless you dont get your injections.
I believe that you are all good with your first pregnancy, and the meds that you recieve this pregnancy are protecting you for future pregnancies.

What if you had an early miscarriage? I miscarried before this baby, and I got the injection at 28 weeks this pregnancy. are there higher chances of complications with my baby?

I would hope that they would have given you an injection... maybe they did and you don't know it.
When I was in the hostpital with my ectopic pregnancy, they gave me one, but I was soo groggy I don't remember. Would deffinetly be something to bring up at your next doctors visit... I had to ask at my last one, cause I was wondering the same thing.

They didn't know I had RH negative blood with my early pregnancy/miscarriage.
