Cheering on my period?

Hey I’m 15 and I’ve skipped cheer every time I’m on my period and I have to go tomorrow but I’m point flyer and I’m scared something I gonna happen when I’m up in a stunting, tumbling, or jumping. any tips for me I’ve never used a tampon before because I find them uncomfortable when I have tried to use one. But I don’t want to wear to bulky of a pad. Please help what do I do?
