Talk to Gynecologist on Unwanted Pregnancy Abortion

My friend is pregnant of two months I think.. This is an unwanted pregnancy. As the father of the child is not in marriage and he left her miserable.. She took medical abortion kit. But had slight bleeding with one clot. Strip test is still positive. No medicine is effective.. She don't understand why the test is still positive. Its been 2 weeks of positive test after taking pills.
