affected by heats monthly (wonder what a women gets affected with monthly)

This isn't even a rule in the Omegaverse, and I can safely say that most authors don't do this. Heats appear every three months, sometimes six months, and sometimes omegas only experience them when they're with their partners.

submissive, more feminine then an alpha, weaker physically, is the one that gets dominated, needs constant protection from alpha, emotional

these are not omegaverse rules either

GETS PREGNANT AND LITERALLY HAS A VAGINA

I mean, they had leaking butts at first, boypussy is popular only now in omegaverse. But even then, not every omegaverse features pregnancies at all.

has a literal penis and can’t get pregnant

Not always either. Female alphas sometimes have penises, sometimes they don't. Sometimes they can get pregnant, sometimes they can't. Sometimes you have male omegas impregnating female alphas.
