Can an Alpha know/sense when their Omega is pregnant if they're bonded? Or is it like irl where they know only when a doctor confirms and stuff.
I think that they do instinctually, but don't realize it. I'm all about a protective Alpha, that's literally my cocaine.
Subconsciously they are making sure that their Omegas are safe. They growl at people getting too close or shielding them with their bodies without realizing it.
In some headcanons Alphas can smell it in the scent before the Omega realizes it, it doesn't work like that for me. At least not exactly. At first, an Omega's scent heightens and the Alpha becomes more obsessed with smelling them. The pregnancy smell doesn't kick in until a little bit later. The pregnancy smells also vary.
Either way, for some Omegas the Alpha's behavior makes them go get a test, Omega misses a heat, Omega just has a feeling, or the Alpha smells it later on.
