Funky smell problem

Hey girls. So this may be kinda gross to some and trust me it grosses me out just thinking about it. But i started BC for the first time EVER and im 24. Im more than half way through my second pack almost to my white pills (im on Sprintec) and i have this odd smell. I SHOWER EVERY NIGHT so no i dont have a hygiene problem and never had this problem before! Im so confused! I have one man im fully committed to since May and yes i have been tested for STDs and i have nothing. Maybe it has something to do with my BC but i have no clue!!!! Any suggestions??? HELP! 🤢😪
