Periods during volleyball tournament

reegan

Sooo I just got my period and I have a volleyball tournament this weekend. I usually have decently bad cramps on my 3rd and 4th day which are the days I’ll be competing. I wear tampons however I always have to wear like a thinner pad underneath and I always feel like people can see it even though they probably can’t so idk what to do. Any tips overall for periods during a tournament?
