bleeding after masturbation

hi! i was not fingering or anything, i was masturbating in a pillow then i got spotting. i think because it was because it was dry or something??? but it makes me overthinking. medj bloated na rin ako or because of coffee ito. then these past few days napapansin ko parang medj brown or parang pinahid discharge ko. i cant go to a doctor yet i am scared sorry huhu
