Hey Ladies!! I'm 13 years old and I just started my period a little over a year ago. I recently just finished my period and I have to go swimming in a couple weeks and since my period is so irregular I have no idea if it will come early, late or right on time?! I am not allowed to use a tampon because of TSS and I'm a little afraid to use one anyways! I have read everything online and it says tampons and menstrual cups are the only option but I can't use those! What do I do ? I don't wanna miss my friends birthday nor do I want to be embarrassed ! I need some real help and advice ! Thanks!
