To be blunt, Matt can likely smell periods (though whether he knows it or is just like 'doot doot doot I had terrible sex ed, gosh I wonder why some people smell like old blood sometimes')

Im wondering about how the menstrual product used affects this. At a standard nose-crotch distance* with no variables like leaks or standing next to a perfume store, I assume he could smell a pad, but probably not a cup. I'd like your opinions on tampons.
Would their location inside the body bamboozle his super senses, or is mere cotton no match for our hero's olfactory abilities?

*I can't believe that's actually a phrase I used
TL;DR: Tampons. Detecting. Can he. Why did this turn out so long and weird
