Everyone Is Saying I Could Be Pregnant I'm Freaking Out! HELP😔

I have never had sex before. I don't want to have sex until marriage. I have severe anxiety though, and everytime my boyfriend and I do something I freak out. 

According to Glow today is my ovulation day. Yesterday, my boyfriend and I kind of messed around. His genitals were never near mine, and the ONLY thing I am worried about is POSSIBLE precum on his fingers that could have entered my vagina. When I was with him, he ejaculated twice, but he also ejaculated that morning before I saw him. He peed after every ejaculation. He ejaculated in the morning and then peed, then ejaculated in the afternoon and went to the bathroom, and then the same thing in the evening. Should I be worried about pregnancy? Could possible precum on fingers actually impregnate me? Especially since he peed after every ejaculation??
