hi if you have just had sex on day 14 then no its not possible? day 1 first day of your period day 14 give or take a day should be your ovulation day his sperm would have needed to have been in side your vagina 3 to 4 days before it takes 3 days for sperm to get in place ok so far then and now do you understand? the only real way is if you miss your next period wait a week then go get tested. hope this helps you. good luck
can you become pregnant two weeks after your period
