If your different blood types then that also wont effect him at all. In the sac they can have a whole different type of blood then you but it doesn't mix because he is in his own little area.

Wow that sounds scary! I didn't know that! Food for thought.......
Baby will be fine! Nothing happens with blood types. If your RH- (have a negative blood type) you'll be getting RH- shots throughout pregnancy, so say your baby has a positive blood type, the shot will prevent your body from attacking the baby!
