hi
i used to spot for about 5 days before my periods. i had an ultrasound in april 2016 and found endometrium polyp.. i had my DNC on 11 may 2016. and after that pre period spotting reduce to 2- 3 days. My gyn. suggested me to take duphaston 10 mg for 20 days along with folic acid in my last visit.

I had spotting on 19 september 2016 and spot till 22 september 2016 , then i had heavy flow on 23 september. i started my duphaston on 30 september 2016 till now but missed one day during this period. Today on 6th october i again had brown colour clots and light spotting. I am worried about it. i have no symptoms like pregnancey.. but i have back pain.
pls guide
