Talk to Gynecologist on Delayed Start Of Duphaston..

Aoa, I had endimeteioma in my left ovary but regular periods always. being married since 8 years and ttc for our 1st i gave another try to a round of lezra| gonadotropin| and then duphaston. my follicle was 21mm and ruptured on time but out of my frutrated condition i forgot starting duphaston on CD15 and instead started a week later (i have memory loss issue). today was my expected CD 4 but still no periods no PMS, excessive urination. what should I expect? is it duphaston actually delaying my periods or should i keep my hopes high for any implantation? p.s i saw a light pink discharge in morning urine but urine test came back negative.....
