Today is Wednesday and my period was suppose to come Sunday gone, however I have not received my period as yet. Yes I am sexually active, however I got my period last month December and haven't had sexual intercourse within the 28 days since my period started in December. I have no signs of my period what so ever, however on Monday a small amount of brown blood/discharge was seen and nothing else after. I am a college student and went home for the Christmas break so I switched soaps also perfume. In addition to that I got sick with the flu and was taking multi-symptom tablets and currently at the moment I have the cold, also I returned back to school and there is a huge change in climate compared to that of back home. Can those be a factor to why my cycle is delayed?
