###Human: Does Duphaston delay periods? ###Assistant: Hello, Welcome to Icliniq. I would like to know the reason why you had been taking Duphaston? If you have been planning for a pregnancy, then it would be advisable to check your urine pregnancy test once. If negative you can wait upto two week for your Periods to come as you just finished your course of Duphaston yesterday. It may Take maximum upto two weeks for the withdrawal bleed to happen once the Duphaston is stopped. If you got pregnant this cycle, then you may not have periods even after 2 weeks. So check.accordingly. please feel free to revert back anytime with any further queries. Have a nice day.
