Tampons make my period shorter?

Sky
This may sound weird idk but I've only started using tampons recently like the past few cycles and it makes my period shorter? I usually go about 7-8 days but it's been going 5-6 (not that I'm complaining). I didn't know if that was normal or I should be mindful of it. It also makes my flow lighter faster by a couple days compared to if I just use pads.
