What follows is an ABO AU prompt. In this ABO universe, everything is the same as our world except everyone is either an Alpha, Omega or Beta, or an Alpha with a Sigma designation. Betas and Omegas cannot have a Sigma designation. The Sigma designation denotes that one can change between secondary statuses, though they cannot will it to happen. It is instead a completely involuntary biological function that triggers with hormone fluctuations. So an Alpha+S (which is an Alpha with a Sigma designation) can go entire time periods in an omega state where they are able to have heats, get pregnant, and do all the other things Omega bodies are capable of. Alphas usually don't know that they have a Sigma designation until later on in life as it develops after they present as an Alpha to begin with. Not every Alpha is capable of having the Sigma designation as it is genetic. Alphas can get tested for the gene. But just because an Alpha has the gene doesn't mean they will develop the designation.
