Thanks for your query.
I will try my best to provide you with best possible professional recommendations to your questions.
Has your girl friend taken the drug after consulting OBG specialist. Drugs are effective only if they are taken within specified period. Usually after taking these pills clots will be passed and then bleeding will slow down and there willll be no bleeding after 6 - 7 days.
Prolonged bleeding indicate incomplete abortion
I advice you to go for pelvic scan and take this report and meet OBG specialist. In case of incomplete abortion, its removal should be done.
Yet again, I do hope that you have found something helpful and I will be glad to answer any further queries.
