Hi I had ICI on 16th and 18th day of my cycle. My endometrium was averagely developed on day 16. I ovulated on day 18 morning. My gynae prescribed duphaston 10 mg from day 19 for 12 days. I had back pain, cramps and light fever on day 27 of my cycle. If my HPT comes -ve on day 30 of my cycle but I do not get periods then should I stop taking duphaston totally or should I continue taking it. Does stopping Duphaston cause withdrawal bleeding. Do I have a chance of getting pregnant.
