Need re assurance ? I cry myself to sleep every night ....

I am seriously under a lot of stress right now tbh I have been stressing about this since the beginning of July , I haven’t had any sex I’m a virgin and Ive never been fingered ... in July tho I did some rubbing on the butt he never came what I’d like pre cum came out and dropped down ... I had a 5 day period and it was regular ( heavy for the first few days and then lighter ) ... then I was so scared that it was implantation bleeding I literally cried every night for what I have done and how am I gonna come out about this ... then second period time rolled around i had cramps and I bled heavy with medium clots but it only lasted for 2 days ... now I’m having this watery discharge that I feel coming out of me like it literally water ... & I’ve took s test 2 weeks after = negative 5 weeks after = negative 9 weeks after = negative

P.s the stress has made my period irregular
