    The pregnancy will still continue even if you develop antibodies. Ask if you've been checked and if not ask them to so that at least you know then. I've had so many shots in the past and I do vaguely remember them saying that if I was less than ten weeks I wouldn't need the shot but then I had a m/c at 8 weeks and was given a shot.

    You probably did have your antibodies tested when you had your first lot of bloods done. Some doctors will do them again around 30 weeks. If you sre worried just ask to have them done again. As previous posters have said, as long as you have your anti-D shots everything should be fine.

    i have A- and df has O+ blood, ive was always told that you only need to have the anti d at 28 weeks and arround 32 and after birth, i know for a fact one of my children have positive, but not 100% on the other 2, even if your patner had negaive blood, you would still need to have the anti d. definitly ask if your worried about anything. it dosent hurt to be well-informed!

    I am o- and my DH is A+ so I had my routine Anti D injections during pregnancy, after baby is born they will test the cord blood to find out the blood group of the baby, if they are also positive you will have an anti D injection after birth. My first 2 babies were both O+ so I had anti D injections after I had them, DD #2 is actually A- so I didnt need to have another Anti D injection after I had her.
