she would want to perform abortion at home but without medicine or surgery.
Parental consent is not required for abortion, as you can easily BYPASS parental consent laws.
Local abortion clinics would be able to help explain this to you, or I can explain further if you like.
The procedure takes about 30 minutes, 20 minutes of that time is setting up. 10 minutes and it's over, maybe less.
Honestly, you shouldn't let your friend do this. She could end up hurting herself. Instead of abortion, take your friend to see your local crisis pregnancy center. They have councilors there who can talk to your friend about her options and help her find one that works for her. They also provide free ultra sounds. Finally, I think it would be best if you told your helped your friend to talk to her parents about this and, if her parents are abusive, help her to get away from her parents and talk to another adult you trust (if you look up Child Help, they help children and teens get out of abusive situations.) I know it sounds scary, but sometimes parents can respond positively to situations like this.
Honestly, your odds of aborting in Pakistan are pretty slim. If you are able to leave the county, do it. Once you are out, look for a crisis pregnancy center. It's not an abortion clinic, but they provide free ultra sounds and they advise pregnant women on their options.
