HELP! Swimming on period! EDIT*

Im 14 and I’m not allowed to use tampons... I’m in the middle of swim tryouts (all week long) and I got my period today! I don’t know what to do 😰 Any tips or advice ???

(EDIT) I searched a little bit and I found a swimwear that is made for water activity while on period!! I just wanna know , Have any of you ever worn one of those? Does it work? And Thank you all
