Usually my periods occur normal with the area of the dates but in this month there is no sign of it I would like to let you know that I am taking pco medication that is pco care forte and glyciphage sr500, folinz. I want to conceive and hence now iam unable to jugge whether iam pregnant or not. If not then y my periods are stopped and if yess then at what stage I would get to know that iam pregnant. Please advise.
