Super heavy period all of a sudden

I dont want to be dramatic but Ive never experienced this before.

My periods have always been not a big deal. No major mood sifts, bleeding but never over to top heavy. Cramps would happen the first day on and off all day and werent super bothersome.

THIS cycle is much different.

Im super sensitive

An emotional wreck

Definitely been in a curl up in a ball pain type. (Tmi but uterus feels likes it has pressure on it from gas??)

Also gassy

Cramps are now sharp shooting pains and Ive had them over 24hrs now

Im soaking through those super long overnight pads

Ive gone through 4 or 5 since my period started late Tuesday night.

Is this normal??

Period also came 3 days early when my last cycle was over a week late.

How much bleeding is too much bleeding?

Definitely feel for the ladies that have this type of period all the time.

Someone reassure me this can be nornal.??
