Period Help please 😭

So I’m 21 no previous health issues and I was wondering when I should be concerned about how much I bleed. For example on my 2nd and occasionally 3rd day of my period overnight I have to sleep with a super tampon in and I make sure I wake up at about 1AM or so to change it if not I will wake up to a mess. In addition during the day after the 3.5hr-4hr Mark my pad is pretty much full and I’m using a super tampon again. I also occasionally get super bad period cramps where it hurts in my muscles to relax to pee.
