I know I’m probably not but would like moral support

Hi everyone! Im a 20 year old virgin and have been freaking out about being pregnant. It may be because of my anxiety but on the 1st day of my ovulation (sept 2nd) My bf and I were messing around and he may or may not have touched his precum on his fingers and then touched my clit. My rational side knows that precum doesnt always have active sperm and that since there was no penetration theres almost no chance of being pregnant. But i made the mistake of going on google and i have had breast pain, nipple sensitivity (and they are starting to look different than what I am used to) and discharge. I am supposed to get my period on the 23rd and I’ve always been super regular. I guess i just need some reassurance :)
