Is it possible to induce your period?

Sara
I'm a couple days late, which NEVER happens to me. I still have my V card, so I can't be pregnant, either.
I've heard about ladies drinking teas or doing certain things to push or shorten their periods a few days, so I was wondering if it was possible to induce it? 
I've had all the symptoms I usually get this week: sore breasts, constipation (sorry if TMI!), breakouts... but nothing came out from those.
Thoughts?!
