Prob nothing but I'm still freaking out

I'm used to a funky cycle; my period's all over the place normally. I've been 30 days late before but never worried cuz I hadn't had sex. My period was 10 days late a couple days ago when I had sex for the first time. Used a condom, though not on the pill. Still haven't gotten my period. Wouldn't be scared about pregnancy usually, but I actually have had sex now and it's a possibility, no matter how small. And since my period is late and I'm new to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, my tracker says my chance of being pregnant is high cuz it doesn't have my history to judge against. Should I be worried? Or am I overthinking it?
