thatd be a fucking nightmare oml imagine your heat and period syncing up
but i think in omegaverse everything really depends on what the author wants, there was one fic that i've read where female omegas menstruation cycles gets completely replaced by heat cycles reply
mine is if the author draws the bottom too plain looking or just simply too ugly for my taste and the top looks like a fucking greek god and vice versa ugly ass top and then the most ethereal gorgeous bottom to ever walk this earth
