Negative blood type with pregnancy?

Sydney Nicole
I am not pregnant, nor planning to be anytime in the near future.
But I have found out that I have a negative blood type and that when I do get pregnant I will have to get a certain shot after a certain amount of weeks to make sure my body doesn't fight off the baby if it has a positive blood type.
(All of this may not make sense to you if you don't know about negative blood types and pregnancy lol)
But anyways it makes me scared for my future pregnancies and things that could go wrong!
Anyone on here have a negative blood type and had a healthy baby? I'm just nervous for it even though I'm not trying right now! Haha
