Talk to Gynecologist on Overdose Of Ecp

My friend has been taking ecp for a year, two tablets for one doze, approx twice a month. She didn’t get her period from november n spotted in January n no periods then. In May, she was told by doctor to diet, exercise n take duphaston to get your periods, she has started the medicine, but is very upset that what if she is pregnant, coz she is unmarried so very confused that which doctor she should go to safely.. she did her pregnancy tests in December n February, tht gave no results, what should she do now. I m very worried for her. She is getting in depression wd sucidal thoughts. Cn she be pregnant even after ecp? Or is it overdose of ecp?
