im 14. so i had the stomach flu i believe like 4 days before my period due date. i still haven't gotten my period i am now 5 days late. i am so worried. could the stomach flu throw it off? i am having symptoms of my period like back aches, tiredness, breast tenderness, etc. i was throwing up for like a day, had diarrea for like 2 days, had a fever for like 2 days and body aches & chills. i felt fine after like 3 days. also 3 days before i threw up i showered w boyfriend and i did again 2 days later. no sex tho just fooling around but what if the precum dripped on me and contained semen? could i be late from the flu and delay my period or possibly miss my period? or could i be pregnant?
