Tampons vs pads

Normally I would use pads and my periods would last 6-7 days 
But this time round I mostly used tampons (because of summer and pool parties and beach everyday etc) and it's the fifth day and I've had nothing and I put a mini tampon in all day and when I just removed it , it was clear with a little blood vessel string and some light brown bits but nothing 
Does anyone else find there period way shorter when they use toons cause it's never been this short and I'm loving it !!!!
