Spotting after masturbating

So I only use clitoral stimulation when I masturbate but recently I’ve noticed almost every time I masturbate I start spotting but it goes away after a few hours. Should I be worried and go see a doctor or is this normal?? Any advise welcome!!

I should note my periods are kinda messed up so I put it off thinking it was just my period being weird like normal but it’s becoming a trend!!
