Silly question about scrub pants

Hello everyone!

I have a silly, and kind of embarrassing question. The required nursing scrub pants for my school are white. Now I can buy white colored/nude colored undies, which isn't a problem, but I do have one question: Does anyone have any suggestions on what to do when it is "that time of the month" when tampons are not an option?

I know this sounds like such a silly question, but I'm genuinely curious! I have had some other nursing students tell me that they wear boxers under their scrubs to avoid VPL (visible panty lines) but that is also going to be noticeable. I just have so many other things to concentrate on that I don't want to have to worry about being able to see outlines through my scrubs, or more importantly, knowing that I have to get to the bathroom immediately while in the middle of clinicals.

Gosh I am so embarrassed to ask this, haha. Thanks for all your responses!
