Hi, im sixteen years old and a little over a week ago I had unprotected sex. Im not completely sure if he finished or not but I know there is pre ajackulation (sorry not sure how to spell it ) And so that has been worrying me. I have become very drowsy lately and have had diarhea for the past few days i'd say. I havent had one regular stool within these days. Could this be a sign that im pregnant? I dont know if im over stressing or what. Please let me know .
