U by Kotex® Ultrathins (and U by Kotex® tampons) are super discreet, so the answer is no…unless you tell them of course!
The aim of the game is to feel fresh all day long, so changing your pad every four hours or so is ideal. If you’ve got a heavier flow, then it may need to be changed more often. Every girl is different.
Check regularly when you go to the bathroom. You might notice a feeling of wetness or dampness, occurrence of stains or the pad may feel heavy in your undies. These are all signs that the pad may be full. In this case, switch to a clean pad.
Why are Ultrathin Pads individually wrapped
This is so that the pads stay clean and sanitary. Also, you don’t have to carry around a whole pack of ultra thin pads in your bag.
Pads should not be flushed down the toilet as they have a plastic backing on them (which is not biodegradable) and they may also block the plumbing system. Schools and public toilets will usually provide special sanitary bins, so place your used pads in there (wrap it in toilet paper first, as the sticky side may get stuck to the bin door). If you can’t find one of these special bins (you probably won’t have one at home), don’t fret, just wrap the pad in toilet paper (or put it in a bag) and then pop it in the bin.
