Aunt Flo might be drunk!

So my period started thursday and it seemed normal and heavy but by friday evening I was barely bleeding and Saturday morning I had light bleeding then nothing. Sunday comes along and barely anything, didnt even really need a tampon. And today I don't have period at all. My periods are always 5 days long and usually always really heavy so my question is do any of you ladies think my period just messed up or should I possibly take a test?
