pregnancy paranoia

ok so i’m 18 and lost my virginity on 1/3 to my boyfriend. we used protection but the condom broke a little while in. we noticed and changed it right away but i’m really paranoid that i could be pregnant. i’m supposed to start my period in 5 days and i know i can’t be sure until then but i’m really paranoid. a friend i talked to said the paranoia was normal and i’m going to be okay but i’m really nervous and i need reassurance. i’ve gotten some of my pms symptoms but i feel like they could be symptoms of pregnancy, even though it’s too early for them to appear if that was the case. i just want reassurance that i’m more than likely going to be okay. after changing the condom he was extra careful and he pulled out so he wouldn’t cum in me and risk it. i know i sound crazy but i’m still worried
