u/7mions

i (18 F ) am on day 34 of my cycle rn which is 5 days late for me. ive been experiencing cramps for about a week , the same cramps i get before every period but 34 days is a longgg cycle. my longest has been 33 but other than that i have a pretty regular cycle of 29-30 days. Im a bit anxious because around the time i ovulated i had protected intercourse (double protected because we pulled out aswell as using a condom) so there was no contact. my question is, how do i make my period come? my friends are telling me to just take vitamin c but that doesnt seem effective ( i am doing so tho lol)
