Confused!!!???

Ok so I had what looked like a vvvfl Tuesday I think? Well I started my period (I think) on Thursday and bled really heavy Friday all day and then Saturday morning and by like 2:00 yesterday it was gone? No more bleeding at all since?! What does this mean, my period lasts atleast 5-6 days normally so this is very unusual for me, please help me figure this out if u all have similar stories. Thank u all so much in advance!!♡
