Get a couple OB tampons and tuck them in your bra.

Put them in a small case

If you happen to be wearing something with pockets then just put your pad/tampon in there it will give you a little more privacy

who calls their period, monthly??

I wouldn't care honestly. Women just understand, and men will do their best to ignore it and forget it. Most people honestly probably won't really notice they have too much else to worry about; including anybody there who actually has to pay attention to whats in the bags people bring in to make sure it's nothing that's not allowed.... they're going to see a whole bunch of different things and won't really pay much attention to who has what unless it's actually a problem. Also, chances are pretty good you won't be the only one there with their period. I get how you feel too though, used to be really embarrassed by mine but life and situations of not always being able to hide it taught me to not be embarrassed. Maybe you could hide a couple tampons in your bra though, if you really don't want everybody to see them. Oh and good luck on your exam.

Sorry, can't sympathize. YDI.

Double pack. Super tampons and ultra pads. 3 days in that should get you through a hell of a lot of time without carrying additional supplies around.

How longs the exam that you're going to need to change midway, also where will you be doing that? In front of everyone? No need to take anything in otherwise.

hey why not put that in a not so clear bag or wrap a napkins around it. just think of some acceptable way to cover it. Good luck!

Try Softcups, my wife swears by them. It should last you ling enough to get through the exam
