Confused

So in this world an omega is a person who has female atrubutes either male or female and has a heat cycle once a moth for a week, when an omega has this heat cycle it releases hormones, which are sexual urges. These hormones are detected by alphas. Alphas are male and females who are of higher society and shouldn’t be looked down upon while omegas are the complete opposite. Anyways an alpha are the only people who can detect an omegas hormones and have xxx with them, they can also mark an omega and become their mate. Which is a life-time partnership. Betas on the other hand are similar to the average human being who can mate with alphas and omegas

If you want to know more you should do your own research

see first chapter

tldr:
b: normal people

a: are the dominant species and can make someone pregnant but cant go preggo thenselves

o: submissive species, can get pregnant

the diff between b and the other 2 is that a and o get ultra horny during a certain period of time(in heat)

Thank you so much this is my first omegaverse yuri and I'm not familiar with the terms so I understand now.
