inducing period? PLS HELP

Ive been having some unprotected sex lately and im worried of possibly being pregnant. im only 19 and in college and im really not ready so im on the pill, but one night i slept over at my boyfriends and i missed a pill that night. my periods supposed to come today or tomorrow, and my periods are usually very light or almost nonexistent, sometimes i skip a month. i heard taking vitamin C can help it come sooner? is there anything i can do do make it heavier or something so i can be sure? i just want my period yall😭😭😭 Im so scared i dont have enough money for an abortion

edit: also im getting over a UTI so can that make my period late?

UPDATE: not even 20 mins after posting this i went to the bathroom and i got my period im so happy im crying ill never miss a pill again thank u all
