I'm going on a beach holiday next month, and I wasn't meant to have my period, but now it's delayed by two weeks, so I might have it! I'm going with friends and I'd really like to be able to swim and wear a biniki, but I've only worn tampons a couple of times, and they weren't THAT comfortable, so I never bothered. None of my friends wear tampons while swimming, so I guess I just want someone to reassure me that it's alright. How does it feel while actually swimming in the sea? It doesn't feel like it's going to fall out?? That's my main worry...and not being able to tell if it's going to leak/if I need to take it out. My period gets quite heavy when I'm in the sun...hmm. I really wish I didn't have my period then (and it's never dealyed by two weeks?!) !
