I experience an kind of echo of my draconic half's heat cycles. I call it an echo, but it's strong enough that is affects my biorhythms in similar-but-different ways than HRT normally does for other trans women. Highly validating, and somewhat positive due to not experiencing period symptoms in favor of heat symptoms!
For me, it's strongest when her heat is active, but since the normal cycle for humans is monthly, i get this secondary echo between months. A sort of "strong" and "weak" heat, alternating. And as her world does not exactly line up with earth's day and year lengths, roughly every two years we desynchronize for about three months. After which we realign on the opposing alternate months.
And yes, my heats affect me strongly enough that my otherkin family/friends with good noses can scent my pheromone shifts.
