How to tell if your pad is full without looking at it? I need to do this for school I only get 4 back room breaks a day

Okay so my number one tip is feeling the weight of it! You can usually feel if your pad is getting heavy, like it's holding liquid. After wearing one for a bit, you'll start to get a hang of knowing when it's getting full just by the way it feels. If it starts to feel a bit colder or damper against your skin, that's another pretty good sign it's time for a change.

Another thing is just knowing your flow. Some days are heavier, some are lighter, so you'll figure out how often you need to change it on those different days. Like, my first day is usually super heavy, so I know I'll probably need to change my pad more often then.

If you're worried about leaks, you can try wearing darker clothes, especially on heavy flow days, and maybe even some period underwear under your regular undies for extra protection. That way, even if you do leak a little, it's not a huge deal and no one will notice. And if it feels uncomfortable or like it's getting too big between your legs, that's definitely a sign to go change it, even if you can't tell for sure by looking.
