this would be an interesting contrast to the sheer amount of oops/surprise babies that seem to be prevalent in the genre already. lots of stories seem to take the "unconventional character/couple thrust into traditional heteronormative normalcy" route even though technically most omegaverse couples that aren't doing the surprise omega trope are normal within their settings. so it'd be interesting by contrast to see a "typical" alpha-omega pair having a "standard"normative relationship that involves explicitly planning for a child.
to really spice it up, that plotline could follow a past abortion.
it's me, an avid proponent of abortions in omegaverses. :D

I don't think omegaverse with planned pregnancy exists. Why is irresponsibly bringing innocent children into the world as usually emotionally stupid and stupid stupid people so popular???
