I have been diagnosed of pcos this month and i also had a folcular study done. I am under infertility treatment and the doctor gave me e-ova m from day 3-7 and according to follicular study i ovulated on 6th jan. My lmp was 23rd dec and its been 25 jan today and i have still not got my periods. I was prescribes duphaston from the ovulation day untill my next periods which has not come. I am still taking it and i did a UPT on 20th jan which was negative.I am having menstrual cramps from 21st jan but my periods are still pending. What should i do? Is it because of duphaston that i am not getting my periods or i could be pregnant? I have no pregnancy symptoms as of now.
