okay. so my boyfriend and i have been having unprotected sex almost everyday for the past 3 or more weeks. (stupid, i know) i havent missed a period yet, but i have some symtoms.i get hot flashes, i have severe light headedness, im eating more, i have weird pains in my abdomen, and nausia. pretty much everything but breast tenderness. is it too early for me to have these symtoms? is it possible for me to be pregnant and not have breast tenderness??
