am i pregnant

okay so me and my boyfriend we're messing around and he ejaculated in my mouth but some of it got on his shirt and he reached down to see how much and then went to the bathroom to wipe it with toilet paper with the same hand and then came back to change his shirt and then got back in bed to finish me and fingered me with the same hand that had touched the semen. i'm worried i'm pregnant and i really can't be in only 15. i'm hoping that it wiped off with the toilet paper or had dried before he got back to me. he put his fingers all the way up in me and i havent really tracked my periods because i'm a virgin and have never done anything like that before and never will again. the last one was from june 7th to the 12th and idk how long my cycle is but i feel like its lay and i have little to no discharge but i have no pregnancy symptoms it's been two weeks since it happened and i have clear watery discharge and tender breasts
