Smelly Period Blood

I didn’t start experiencing this until this year. My period blood smells. It’s not like the typical metallic smell. It’s not fishy either. I can’t really describe how it smells cause each time it’s a little different, but the closest thing I can describe it to is garbage. Even that doesn’t describe it. I haven’t done anything different this year. Same food. Same guy. No STDs/STIs. I don’t experience any bad smells outside of being on my period. No bad discharge. The only thing I can say is I did randomly get a yeast infection and BV earlier this year for the first time. From then to now I have had a few more unexplained yeast infections, but I’ve been doing good for awhile now. And the weird thing is my period blood doesn’t smell each month. It’ll smell normal for a couple months then the next month it’ll smell bad. It comes and goes as it pleases. Any idea what could be going on?
