Volleyball camp within a few days are there ways to prolong my time?

I have to move about to volleyball camp and my interval is due almost the exact day I be in motion. I have horrible cramps, and hefty flow. Is there a mode to make my time of year come earlier so it would be stale when I go to military camp? Or a way to fashion it to I skip my period.
My mom wont agree to me take medication, so a way to do this instinctively.
Answers:

Progesterone deficiency and stress.?

No, sorry. Without medication, in that is no way to change/control your cycle.

Some times when I own sex I get adjectives swollen? Is that normal?

I don't see why you would want to prolong it. most girls want to shorten it. If you have it in mind postpone it, you can postpone it if you're on birth control and skip the sugar pill pack and just shift right to the next months pack. That's the merely way.

You could try the depo shot, that's not a pill, but it's not exactly automatic either. There is no agency to prevent your period instinctively, because it's natural to own it.

Have you ever heard of "skin tags" ?

I play volleyball also and sometimes the more alive you are, the less bumpy the cramps are. I also learned from experience that when a girl overworks her body her term could be postponed for a week or so, although i wouldn't recommend it. I played in tournaments on weekends that last all morning and found that I missed my period once because I played so complex. Just be sure to drink lots of water.
