What it does is making the cervix soft. That is how it's used to get your period back. Some think they can use it for abortion but once the egg is attached to the uterine wall it's too late.
Not for abortion since you put this in the abortion category, but when your period is gone for other reasons and the doctor prescribe it to you, yes then it works.
Well i have to admit, when i was 11 i wanted to work also, but sadly u can't get a real job. As in real i mean: Be employed by a company or business, get paid by a manager/owner, and have a paycheck...
