am I just being a nervous reck or could i possibly be pregnant?

okay so i’m really worried i could be pregnant i just need to know if i am or not or if anyone can tell me if it’s even possible, so i was with my SO and we were both completely naked i just started the pill and i was only on day 5 (cryselle is my pill type) we did not have sex so his penis did not go into my vagina. (im 15 btw) he rubbed the shaft of his penis for 10 seconds (this was the only interaction he had that involved him touching his penis) he then fingered me but he was almost certain that there was absolutely no pre-cum on his fingers. his dick did go up near when he would come up to kiss me from when he was giving me oral but i would take my hands and block my vagina off from his penis even touching it. I made sure his penis did not make any contact with my vagina. Is it possible that i could be pregnant ? or am i just stressing myself out for nothing ?
