soemwhat frequent spotting

so my period was from the first of this month and was for five days, then on the 17&18th I was spotting after having some me time, and today it happened again.

*bit of back story*

the 28th of last month I got blackout drunk with my friends (first time successfully getting drunk) and then the three of them ended up taking advantage of me and taking turns and stuff.

should I be worried?

it was clitoral stimulation only
