Are my roommates right for worrying about my period?

I got my period back in middle school, and it has always been pretty intense. it comes regularly now every 20 or so days. the only thing is that the flow is ALWAYS heavy. It is always so heavy that I can't wear regular tampons. My "regular" are super plus. and I always have to pair a pad with it because it is a murder scene. What is even worse are the terrible cramps I get for the first two days of my period. They are always constant and hurt so bad that I often become nauseous. I'm 19 now, so I'm very used to my periods like this: fairly short time between periods, intense cramps, and extremely heavy flow. However, since I've started rooming with two of my friends, they have voiced their concern over how intense my periods are. My mom says she thinks it's normal. My roommates are begging me to go in to the gyno to get it checked out.

Any thoughts or advice would be greatly appreciated. Thanks 😄
