Overthinking?

Okay so hi, I am 17, a virgin, about 2 weeks ago I was with a guy where he jacked himself off in the shower while we made out and he came on my back but had his dick pressed against me when making out. Not in me at all since haven’t had cherry poppped, Since then my period is apparently 8-9 days late, but also along with that before this month I suffered a car crash and been stressed from going to court to fight tickets and the crash and started a new relationship which is great but I’m nervous and stressed from my job, this coukd just be stress and no pregnancy? It says I’m 9 days late but I I’m just overthinking this right?
