spotted for 5 days before I got my "period"

I've had My period for 5 days now 
But I was really light and just spotting 
At times I wondered if it was an actual period 
Nah fam. Day 5 and I'm now niagra falls 
I'm in so much pain. Can missing a period cause a really long one? I don't see this ending anytime soon. It basically just started.
