So worried

sophie • Wales

Hi everyone, I’m really worried. I’m 15, and I had sex with my boyfriend about 3 weeks ago without a condom but he didn’t cum inside me I never let him and it was literally about 30 seconds as I worried. I’m now 5 days late to my period. I’m sorry if this is a stupid question but could I be pregnant? He said he hadn’t cum in the day so that there would be nothing on his penis if he hadn’t washed it, I’m just freaking out.
