Nauseous About Female Anatomy?

Whenever I hear about female anatomy, giving birth, inserting/removing an IUD, I get light headed and nauseous.
In high school, we watched the Miracle of Life birth video (the 70’s version) and I fainted while sitting at my desk.
I don’t understand why this is- I’m female, born female, why do I feel like this?
