Pregnant ..)

So I had sex Oct 22 -unprotected

He finished but most of it or maybe all of it not really sure was in my mouth

I haven’t had a period since I had some light bleeding and a little came out when I would pee. I had finished my period a few days before the 22nd

(No std’s all clear on those) I haven’t really had any preg symptoms I think I’m just being paranoid

Advice ?
