inducing a period?

Hey y'all!! My period is 18 days late !!! I can feel it but it won't come out !!! I've been PMSing for the past 18 days and I know it won't go away unless I get my period!! Any one ever make some sort of home remedy to induce their period ? And no I'm sure I'm not pregnant lol I'm a virgin and in a LDR 😊 thanks for any ideas !!
