I LITERALLY HATE THIS GAHHHHH

So about six months ago I got my first period, they were pretty easy, now I am having like a ton of blood and like all of my undies are literally ruined. Oh and surprise surprise, I thought it was over today so I didn't wear a pad...NOPE!!! I HAD TO ROLL SO MUCH TOILET PAPER UP TO TRY AND NOT BLEED THROUGH!!! I'm actually so grateful I wore black shorts though and like I almost bleed through which is a first for me. What happened to my three day, low blood loss periods. I don't really get cramps ( knock on wood) but like I've ruined so many undies :((((
