weird discharge?

so i’m still a virgin, but i do have a partner that i don’t see regularly but do see often. he came over and we had some fun things go on. he fingered me, and ive experienced a lot of pain in the past so he was very gentle this time and it was GREAT. but OF COURSE, the next couple of days until now (5 days later) i am having weird pink, red and now BROWN discharge. i don’t feel comfortable showing pictures, BUT its sticky and it looks kinda like period blood clots, but im on bc and its not my period week. any clue what this could be?
