Talk to Gynecologist on Prolonged Periods

Salam doctor. My problem is that periods have exceeded to day 8-9. The flow is normal for the first five days, rest of the days its bare minimum. But on 8-9 day, there is hardly anything on pad but when i swipe it, i find fresh blood. It doesnt reach the pad but still its there so i cant take ghusl. I did consult a gynecologist forlong periods so she prescribed transmine 500 and postone fort from 3rd day for three days but still the length of days stays the same Please help me with the issue. I want to be done in 5-7 days maximum. Should i change medicine ?
