can anyone help?

i have been diagnosed with severe hypochondria. lately it’s been taking over my life and i had sex with no penetration (manual and oral) but cannot stop obsessing about whether precum was on his fingers or not. i have convinced myself i am/will become pregnant and its only been 2 days since the act. i’m 6 days away from my period and don’t think ill make it until then and am worried the stress will delay it and worry me even more :/ i need closure really bad. i can’t tell if i’m feeling fake symptoms from the hypochondria, pms symptoms or pregnancy/implantation symptoms :-( i feel like i shouldn’t worry because i’m a virgin (never any penetration) but i can’t stop obsessing
