After abortion bleeding. Till what date?

My wife took mifegest kit on 8th july2017, after that she started bleeding from 10th july to 17th july 2017. Then again she bleeded on 25th july till 30th july.we referred the case to akash hospital and doctor referred for ultra sound examination. Post examination the result came as ET 14 mm and no adnexal mass seen, breif details of examination is attached and doctor referred for D&c butWe  dont want to go for D&C  and Hence, referred to Max hospital, saket. After meeting the gynac, she told no D&C required as major parts has  already been washed, and remaining can be dine through medication. She prescribed TEXAKIND MF, METHERGIN( for 3 days) AND RICHER CR (1 mnth). Now, after completion of dose on 5th aug, she again started bleeding from 11 aug till now. In between those days, some times the blood was heavy in form of clot and some times it is only brown discharge. Is this occurance of irrregular bleeding is normal. If yes, till what date? Is this is normal for all medical abortion.
