Wearing a tampon while I don't have my period?

Sometime between Monday - Friday this coming week I'm do to my period. But also Monday - Friday I have a dance intensive camp from 8 -5 each day and since I have to wear a leotard I have to wear a tampon and I can NOT have my period while wearing my leotard. Can I wear a tampon Monday morning, and take it out halfway through the day and if there's nothing on it, take it out and put a new one in just incase? Or is this bad for my body?
