HEEELP! Can you make your period come earlier?

heeelp!-can-you-make-your-period-come-earlier?

I’m going on a one week vacation in two weeks, and I’m gonna get my period on the vacation, which is VERY inconvenient, seeing that the vacation basically consists of swimming. D:

I’m not a big fan of tampons – I don’t trust them at all.

Is there anything I can do to make my period come earlier?
