Probably a stupid question

So iv had unprotected sex (yeah ik stupid) and I'm not in birth control however he didn't cum inside of me at all and pulled out in plenty time this was about 2 weeks or so ago and iv had period symptoms for about 3 to 4 days (cramps, sore breasts ect) I usually only get one day of symptoms then I'm on and my cramps have been worse then ever my period is due today (11/9/19)and still not sign should I be worried?

Edit I do apretiate replys but I won't reply because I woud like to say anonymously
