I like to use pads to make diapers? Normal?

I'm 14 and I just hate asking to go to the bathroom during school (I just started 9th grade). It's so awkward and the school bathrooms are disgusting. So I just take about 5-6 giants pads and make them into a diaper by sticking them throughout my underwear. I also put a few liners around the edges to protect against leakage. So if I have to go to the bathroom... I just go. I've done this a few times and it works very well. Nobody seems to notice. Does anyone else do this?
