So you want 5 to 10 different pregnancy arcs with the game's female deuteragonist?
Do you realize how fucking impossible that would be at this point in the game from a design standpoint?

.
If the devs decided to do that we could all say goodbye to any other plots for a couple years unless they went the CoCII route and just yeeted the offspring into a nursery to never be mentioned again except as a stat-line.
Even if the game was purely catering to the NTR/Pregnancy crowd it'd take a stupid amount of dev time to do.
In AII best case scenario you get Andras or Rowan impregs, a mystery fate baby that pops out the womb the same no matter who you are fucking, or a Jesus baby. AIII you could have more branching.
Game is too realistic to have the deuteragonist become pregnant and it not consume a large swath of plot. Multiply that by all the different routes you want, the amount of time in the game we have left, and also include a non-pregnancy route b/c not everyone wants that and you're starting to have real problems.
