Quick period question πŸ™‹πŸ½β€β™€οΈ

Ok so my period is due to end on saturday but thats also the same day as the pool party im supposed to attend and due to birth control my period is unpredictable it may stop it may go on another 10 days πŸ€·πŸ½β€β™€οΈ my question is if im still bleeding is it ok to put a tampon in and still get in the pool ? Or should I just not go πŸ˜” I just dont want any jaws scenes as ive never done this before do they make tampons or other feminine products for swimming ? you would think at 24 i would know these things
