leaking 😳😣

I'm constantly leaking discharge. I usually don't wear underwear (because I like the feeling of commando) but when I do, they get so wet and sticky and on the weekends ill change my underwear at least twice a day. also at school I will go to the bathroom 7-8 times a day just to wipe myself and my panties or the crotch of my leggings. it's usually light yellow or clear but it's almost always heavy. it has times when it is lighter but it's random. I wear tampons on my period cause I hate pads I know I could wear a panty liner but I hate carrying then 24/7 and I hate the feeling of them. what could I do??? -I'm 17
