Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Deviry is a progesterone hormone containing tablet given to you as a contraception. Since you are having delayed periods, and may be since you have discussed with your doctor that you do not wish to conceive, the doctor has given this tablet as a contraceptive. Deviry Tablet is a progestin (female hormone). It works by replacing the natural progesterone hormone that the body is unable to make. This treats painful, irregular or absent menstrual periods. It also prevents an overgrowth of the lining of the uterus. She has called you to come once you have periods, just to evaluate in detail the various causes of delayed periods. An ultrasound scan may give a clue to the diagnosis. PCOD may be one of the cause which has to be ruled out using Ultrasound scan and blood tests. I suggest you to go accordingly as suggested by your doctor. Hope I have answered your query. Let me know if I can assist you further.
