i had my period for about 4 or 5 days. the last day i had it was the 11th. then on the 12th me and my boyfriend had sex. and he told me a few days later that he is scarde that im pregnant bc we didnt use a condom. i have been having a few pregnancy symptoms lately and not REEEEALLY think im pregnant. we are both 15 and honestly we want a baby but we r still scared about the whole situation. what are the chances that i am pregnant?
