- I have PCOD and do not get my periods regularly ever. My husband and I are trying to have a baby. I am on Duphaston 10 mg, which I take from the 20th day of my periods to get my next periods. This time, my periods were due on the 10, but, I observed spotting from 5th onwards which continued till 12th. I did a pregnancy check at home on 6th, but, found that to be negative. What could be the reason for spotting? Is it normal? Is there any action I should be taking in this regard? Is it possible that I could be pregnant and the urine test is not showing it? Doctor prescribe me take a meprate 10mg for three days I am already taken this is 4 th day I have till spotting what is the reson?
