How to prevent period leaking in swimsuit, help!

Megan

Since giving birth I have tried using tampons, cups, and discs but I leak with all of them pretty much immediately. I’m going to the beach next week on vacation and of course that’s when I’m due for my period. I tried ordering period swim bottoms but they didn’t fit and I don’t have time to order more before I leave. Not on birth control so I can’t just skip my period by skipping that week of pills. Any ideas?? I’m really bummed because I really don’t know how I’ll be able to swim without leaking all over.
