Maybe that's why you don't know of any women that had one - they didn't talk about it.
FREE birth control was available EVERYWHERE to EVERYONE, at ALL TIMES. If a woman or girl got pregnant, she either WANTED to get pregnant, was too ignorant to know about birth control or was too young AND ignorant to know what she was doing.
Also there was and still is abortion on demand for ANYONE, ANYTIME and almost up to the sixth month (I think).
Some were do dumb that they thought that when they got a baby, the government would then support them. They were right on that one. So, we now have GENERATIONS of fatherless boys...not a predictor of success for those males.
