WILL I GET PREGNANT???? (18F 18M)

guys so my bf was bottomless but I had my skirt and undies on and a pad bc I’m on my period. he didn’t finish but I can’t rmb if he had pre*** but even if he didn’t it wasn’t a lot. Based on what I researched on Google, chances are minimal but still I just want reassurance bc I’m rlly scared of getting pregnant and I rlly regretted it. I was planning to get a pregnancy test kit to see after like 14 days. so like what do yall think? Pls help a girlie out tysm!
