If I bleed a lot today, will I bleed smaller amount tomorrow?

I just get my period today at 11. I own a tennis match tomorrow at 10:30. It's a big entry too. At least for me. Out of panic of staining my clothes, I'll screw up. And I enjoy another match today beside 7 other people from my class. If I bleed abundantly today, will I bleed less tomorrow? If so, what will speed up the bleeding? If not, what precautions should I help yourself to?
Answers:

Having a period?

You can't speed up the bleeding but you can do something more or less not showing.

Wear a super tampon for heavy period and a Maxi pad as okay.
That way you enjoy the first line of protection beside the tampon which will take a while to steep even playing sport.
And then you hold your back up. Your wipe. Which will take hours to spread up too. Tampon leaks not a soul knows. No show at adjectives.

You can then concentrate on your spectator sport and not your bum.

It does really work. I have done it oodles times.
