Talk to Gynecologist on Gynecology

27 year old female and have pcos,trying to conceive. Taking fertizol and myfol from past two weeks. My problem is I am having period cramps from past 11 days but got no periods. Firstly pain was in whole lower abdomen now its just sharp pain in uterus that comes and goes and lasts for half minute especially when I take stairs or bend. My cycle is around 24-27 days but today is my 31st day and still haven't got periods, also feeling a lot of weakness.
