My doctor forgot...!!!!!

So I went in for my 35 week check up today. Every thing seems great! Until I ask when I should be getting my Rhogam shot! My doctor pauses and says "you haven't gotten it yet??" ummmmm really?!? So he says he's going to get it ordered now and sent me to the hospital to get it done.

How could they not have noticed this?!

Whats scaring most is can this have a negative affect on my baby?? How do I know if my antibodies haven't already starting attacking my baby??

I am beyond pissed about this!! What if I never said anything?? I was supposed to get this done at 28 weeks!

My blood type is B- and I believe my husband is A+.

This whole situation is just ridiculous. These people at the hospital are looking at me like "why did you wait so long to get this done?"
