Kind of gross...could my cat be into this? (See details)

The cat in the house I am temporarily living in sleeps on my bed with me. She usually doesn’t snuggle up close, but now that it is cold she’s been coming under the covers with me and letting me hold her while we sleep.

The weird thing is that she also started licking my hands. She’s done it every night for about four nights now, after never doing it all summer.

I thought about what could be on my hands that’s tasty that isn’t usually there, and I thought of only one thing: period blood. I’m having my period and since I use a menstrual cup, it gets all over my hands. I wonder if the cat senses it even after I wash my hands well and likes the smell/taste? Vaginas do smell like tasty fish.

Has any one else’s cat done this? Any ideas?

Sorrrry for the visual.
