cyst or pimple on vagina?

hey guys so today while i was washing down. there i noticed a bump and looked and it looked like a pimple or something.. i’ve never had one before but it’s located like on in the middle of the libra minors and the libra majora. it’s not paninful unless i like try to squeeze it. i haven’t shaved down there either because i’ve been on my period. is there anyways my pad could’ve caused it or something?
