Hi, i have PCOD since last year, after taking OCP s for 3 months then my periods were regular till 6 months. But itz been 2 months now i havent got my periods, therefore gynac recomended deviry 2 tablets for 5 days , i took it for 3 days but on 4 th day i forgot to take it therefore i resumed to it on 5th day,skiping pills will cause delay in periods or any other problem?
