Hi do I have to change my pad every time I use the toilet? Btw I haven't started it yet

Okay so no, you usually don't have to change your pad every single time you use the toilet. That would literally be so annoying and use up all your pads so fast.

Most of the time, when you pee, the pad stays totally fine. You just push it a little to the side or hold it so it doesn't get wet. If it does get wet with pee, then yeah, you should definitely change it because wetness can cause irritation and just feel gross. But if it's just blood, you're usually good to keep it until it's full or it's been a few hours.

How often you change your pad depends on how heavy your flow is. On a heavier day, you might change it every 3-4 hours, or even more often if it feels full. On lighter days, you could go 4-6 hours. Just always check if it feels damp or heavy, and if it does, it's time for a fresh one. It's really about comfort and hygiene.
