Bad menstrual odor?

I've never had an odor issue with my period, but this one smells horrible. It doesn't even smell like a regular period at all. This is going to sound a bit strange, but it actually reminds me of bad breath. Luckily, you can't smell it standing next to me or anything, but I can smell it when I go to the bathroom and it's much worse when I change my tampon.

I use Summers eve wash in the shower every morning and even keep the wipes on me to use throughout the day, but nothing seems to get rid of it.

Has anyone else experienced this? How do I fix it?
