Will a diva cup help? (TMI)

So I’ve noticed after my period(i use tampons) I smell pretty foul. Foul enough that I don’t want my husband to even be near me. I feel like I can smell it myself as well even with my pants up. After a week or two the smell goes away, but that’s way to long and it stays so long that I start freaking out and thinking somethings wrong with my vag. If I get a diva cup will it help this problem go away?
