Does a woman actually knows who she's getting pregnant with?

My 1st boyfriend turned out to be a liar, a scammer and a cheater. Years later he blamed me for not wanting to have a child with him. I once told him ''If you ever get me pregnant, I'm going to abort it. I ain't having babies with you''. For some reason I used to dread the idea of getting impregnanted by him. I even told him ''I don't ever want kids''. I was so much against kids when I was with him.

With my current boyfriend, hell yes. I do look forward to bearing his child. He made me change my mind about kids.

If even a guy is a jerk and user and she is too naive, does a woman usually knows who she's getting pregnant with?

Now I feel great to have dodge a bullet with my 1st relationship. I feel great to deny him parenthood. He supposedly wanted to get me pregnant at some point but I scared him when I told I would abort it.
