Wth is up?

I knew I was going to start my period in a few days Be I haven't had much pms signs besides sore boobs and nausea. Yesterday I stated spotting which I usually do then last night I guess I bleed but it looked all like brown like when you get off your period. And when I wiped it was some bright red spotting or Nothing. And I've been having some slight stomach cramps this morning,  I just feel bloated in my stomach but it looks normal. Is that normal?
