Too much bleeding

Just background info I’m 15 5’1 and weigh 109.... so I started my period yesterday and it was very light well today I went through 3 pads by 9 am then at 9 I put in a tampon and had a pad on and 7 mins after I put the tampon in I bled out of it and FILLED THE PAD. Ik I didn’t put the tampon in wrong I’ve been using them for years. I don’t feel sick and my cramps aren’t too bad. Is this normal
