You made a Choice not to use BIRTH CONTROL.
Birth control is NEVER 100% no matter how hard you try.
Not having sex is still the best way to avoid getting pregnant.
That said, I have no doubt that many who fall pregnant and have abortions were not as diligent about birth control as they should have been.
Even back when I was a teen, like in the early 70’s, I remember catching part of a documentary where a hooker was being interviewed and she said she’d regularly end up getting pregnant and before she showed would get an abortion. That way, while she was pregnant, she wouldn’t have to worry about using birth control. And then the cycle would repeat itself. She basically used abortion as her birth control.
I was never so disgusted in my life and could not stand to watch the rest of it.
