How shoulda period feel? What‘s normal?

Hey ladies, I’ve always wondered and thought about this... “what is your period supposed to feel like?” - “What’s normal, what isn’t?”

My periods usually go like this-

Day one- cramping with pain in lower back/front . Heavy flow (sometimes clots/‘oozy blood)

Day two- still pain in lower back/cramping - heavy flow (sometimes clots/‘oozy’ blood)

Day three- mild cramping, flow isn’t as “clotty” and heavy

Day four- no pain. Flow is light

Day five- still light flow but lighter? And usually brown

Day six- stilllll brown.

Day seven- ? Very light brown

❗️I have a bulging disc in my back. So that is why I usually have really bad back pain ❗️

But WHAT exactly should a period be? Pain wise? And is it normal to bleed for 4 days and still have brown spotting for another 4days

How to know-if something is wrong? “Too much pain”?
