To prevent or terminate ? Prevention would be methods to avoid pregnancy like abstainence, the use of contraceptives or pull-out mehod etc etc.
But interesting what you wrote. These are harmful methods. They should def see a medical specialist but I would suppose that seeing a doctor in some under-developped country may not be possible or abortion itself is illegal.
You are right bro. I guess they went through those methods because they had unprotected sex. Instead they would have just made use of condom or post pills although we no that they have side effects and are not 100% effective. Abstainence is still the best.
