Am I overthinking?

I had sex on the 5th of September. We DID use a condom BUT stop due to the fact I was uncomfortable due to the fact I could be ovulating. He did rub his penis on me and around my vagina and rub it but did slightly rub the tip of his penis on my vagina (without a condom on)

My question is there any way I could be pregnant?

I’m overthinking bc I’m not sure if we actually practice safe sex.

I going to buy a pregnancy test later today but I’m not late my period is due in 4/5 day (i have 2 period apps) I was thinking about getting first response 6 days or sooner test
