I'm not even sure 99.9% of all sex was their choice, much less 99.9% of all pregnancies, and if you think 99.9% of women seeking abortion do so for a pregnancy they chose...I'll be charitable and assume you meant something other than what you said.
As to getting pregnant = reproducing, cool, so once they're pregnant the job of reproduction is done and their obligation is over. Any lingering remnants are irrelevant and can be disposed of worry free, since all reproduction entails is getting pregnant and that's already happened.
Forced abortion would be a violation of reproductive rights, same as forced gestation, because both of those force an action on someone who didn't chose it. Luckily for the religious right, "reproductive rights" aren't officially a thing, and therefore cannot be violated. How convenient for them.
Speaking of violations, rape is a violation, but not of reproduction. Not all rapes result in pregnancy. (Hell, some republican talking heads have made the argument that pregnancy from rape isn't possible.) But if a pregnancy did result from rape, abortion would remedy that issue.
When abortion isn't allowed, it isn't the rapist who violates a woman's reproductive freedom, it is the law forcing her to carry a pregnancy to term against her will. (Unless she seeks whatever help she can find in the shadows, where reproductive healthcare is being pushed, and therefore places her at a much higher risk of complications.)
People who think the categorical prohibition of abortion is a humanitarian act are deluding themselves. During alcohol prohibition the government cared so much about protecting people from the evils of drinking that they voluntarily handed production over to the criminal underground and deliberately poisoned industrial ethanol, all in the name of saving people from themselves. It worked so well that it resulted in more American deaths than the Vietnam conflict, made Al Capone rich and did absolutely nothing to stop alcohol consumption. But hey, at least the prohibitionists got to pat themselves on the back for being such morally upright people and forcing their beliefs on everyone else in the most misguided, myopic way possible, despite how catastrophically counter-productive it was. That's worth something. And it's good to see that proud tradition of blind pigheadedness being continued in abortion-prohibitionists today.
