How often do you use tampons during your period?

Jada
I don't usually like them on my heavy days, but towards the end I use only tampons because I feel like it helps clean stuff out, so I don't have to use or douche or something. 
Also, I am fully open to other ideas on how to cleanse after my period ends. Because before I started doing this system, it would be like 3 days later and residue would still be coming out. It makes me feel really icky.
