If you are pregnant about 9 weeks and have sex with someone else other than the baby father will it change who the father of the baby is?

Absolutely not!

I think someone needs to learn a little bit more about how all of this works...

Are you serious? You really shouldn't be having sex if you don't even know something as basic as this.

Do you know how pregnancy even works? Obviously not.

Scary what this world is coming to.
