SOMEONE HELP!!!

so here is my situation..it’s going to sound so weird...so i was with my boyfriend, and we were at the movies and i got horny, so we went back to my house, and while we were there i asked him if he had a condom and he said no! but i was in the type of mood to like not care at all, but we both cared enough to grab a plastic bag, like a little ziplock bag and use it! (I KNOW STUPID) but in the middle of it he stopped to make sure it didn’t break, and i didnt then we continued and when he finished he pulled out and the bag was bloody with my blood, it didn’t hurt and i stopped bleeding immediately after, i tbouvkt it was just me popping my cherry bc i never had sex like that. but since the bag broke he got me plan B so we didn’t worry. it’s been like 5 or 6 days and i was spotting, but i thought it was okay then today it’s like thicker and more like a period then just some bleeding like if the bag cut me. i’m so scared. has anyone had a similar experience??

PLEASE HELP
