A little worried?

Jo

So my boyfriend and I sort of had unprotected sex? He put it in, and thrusted a few times, but I told him to stop because we dont have a condom. I know that precum has low chance of getting you pregnant, but I still worry about it. Havent had my period yet, but I’m very irregular, so it comes every month or so. Could I be pregnant? I haven’t experienced any symptoms
