okay i started my period 2/22 and ended 2/26 and on the 27th i had unprotected sex. then that friday and saturday (3/2-3/3) i had unprotected sex again numerous times. now im wondering if im pregnant because i am having weird snot like discharge in LARGE amounts and my boobs are unbearable. also im feeling very out of it and a little crampy i feel fine when i lay down but when i get up and start moving around i get nauseated and have been running a low grade fever. im starting to wonder because two of my girlfriends are preggo and they told me i am most likely to get pregnant seven days before and after my period. well, thats what their doctors told them. should i wait it for af or test in a week?? thanks
