Helppppp so scared

Well I'm 14 dpo and AF is a no show. I did have unprotected sex the day of ovulation but he pulled out before he was even close and he peed before. Ever since 4 dpo my left nipple has hurt and only my nipple. 12 dpo my boobs started to hurt alittle (only the bottoms) I haven't had PMS or pregnancy symptoms either, none. No bigger boobs, no darker nipples, no cramping, no bleeding, no backache, no nausea, no CM nothing. I'm on vacation and can't test right now but I did test 11 dpo and got a negative. What should I do? Do you think I can be pregnant?
