I have pcod and have irregular periods. I started talking meprate 10 mg from 30th June. But on 1st july i began to bleed. But it lasted for a few hours. I completed the course of meprate 10 mg. But the bleeding is very scanty and it happens on someday while it's absent on the other day. I have extreme pain in my legs and lower back. What is the issue? And when will my periods come? Do I need to take any other medicine?
