Hi, I am under pcod treatment. Doctor had advised me take duphaston (d 18-28) .but this cycle I did not take it at all. When I am under medication the periods date were always on 12th of every month. As I did not take duphaston this cycle, I started to have brown mild discharge today. Only while urinating and wiping can see the brown discharge. Is the brown discharge because of pcod (not taking duphaston) or implantation bleeding? Kindly advise what to do. Thanks.
