I’m so scared

I went on a date with a guy a few days ago. He started to get a lil handsy and asked if it was ok if he could touch me. He was very sweet about it and asked for my consent so he did nothing wrong. I just wish I would’ve said no because it made me rlly uncomfortable. He touched his penis then rubbed my vagina through the leggings I was wearing. I am worried that there was precum on his hand and it soaked through my leggings and got into my vagina and that i might be pregnant. I was wearing thin leggings and a thong. I am a virgin so this is all new to me. My period is supposed to be here in 7 days but i’m so worried. I really wish i would’ve just said no like i wanted to and this could’ve just been avoided. It’s all my fault. :(
