Had D&C Done For Hyperplasia, Next Cycles Also Bleeding Wasn T Stopping. Advised Primolut. Why Is It Happening ?

hI DOCTOR, i had a D&C done in Oct, 2012, due to heavy bleeding lasting 21 days. it was detected to be a case of simple hyperplasia without atypia. the doctor gave me tablet meptrate, 10 mg for a month.in my next menstrual cycle, the bleeding wasnt stoppimg so i was shifted to Primolut N 5 mg , 3 times a day for one week. reducing it to twice a day for the next week and then once a day for the next one week. i was to stop it after a 3 week course, next cycle i was to start again on the 1st day of my cycle taking it once a day for 21 days.after this course i stopped taking Primolut N.i was hassle free from jan 2013 till june 2013, when i missed my periods again for a month. i had my cycle on 28th july 2013 after a gap of a month with very heavy bleeding which has been going on for tjhe last 11 days.should i start taking Primolut again ?or do i have go in for another D&c now. i would rather not do a D&c as everthing was alright with the last biopsy report. please advice.
