Bad smell at the end of period?

I apologize in advance, I know this is kind of gross.

I’ve noticed that with my last few cycles, as my bleeding slows down to just spotting...it stinks!! Bad!

It’s only the last two days or so of my period and then everything goes back to normal.

I thought infection at first, but wouldn’t that contribute to cause an odor throughout my entire cycle and not just the tail end of my period?
