So scared!! Please help!

So I only lost my virginity last monday (circled in yellow) but now my period is late by 7 days and i’m freaking out more and more as each time i wipe and it comes out clean 😭😭

A condom was used and he did not even finish inside me, however i didn’t watch him put on the condom could there any chance somehow he touched his precum then put the condom on somehow cross contamination ?? My mind is racing for possibilities because i’m just too terrified to even think i’m pregnant 😭😰

Normally the gaps between my periods can be 2-4 weeks but is it just coz this time i had sex the thought of an irregular period is making me have mad anxiety or??
