my guy and I had unprotected sex on March 19th, and it's now the 29th and my period is 6 days late, he said he didn't cum but I'm still worried, because can't you get pregnant from pre-cum etc? I've also started exersizing more frequently the past 2 months and traveling so that could also be contributing to it being late. but I'm also 17, so I'm paranoid as all heck and need some advice. SOS guys plz
