PLEASE HELP???

I had sex on November 4th. My period is now two days late we did have unprotected sex but he didn’t cum because I stop him in like 2mins into sex because he didn’t have a condom on and we never resume to have sex is there a chance I’m pregnant even if he didn’t cum? But like I’m stressing my self out because I feel like it’s no need for me to be worrying if he didn’t cum and ik stress could delay your period but my period never been more then a day late.???!!
