help me!!! dry hump freaking out.

long story short, we dry humped on my ovulation day. we were fully clothed and he told me he didn’t ejaculate but a part of my mind just believes a little came out and somehow slipped through the clothes. I got my period for the month but it was odd flow. not exactly like implantation bleeding I don’t think. my period ended on the 8th (4 days ago). NOW TODAY I HAVE TO PEE LIKE CRAZY!!!!!!!!!!! my pee frequency has been on and off everyday. I also have dry lips, throat, swollen lymph nodes and diarrhea and I think my spleen is hurting. I don’t know what the heck is going on. please someone reassure me that I can’t be pregnant. I’m only 15 and I’m so so so nervous. Ps I took two pregnancy tests and they were negative but I think I took them too early :( now I have cramps too ugh
