The result of the pregnancy poll on my Patreon shows that about 70% like pregnancy, 20% don't like it, and the rest have no strong feelings either way. This is what I wrote about the result of the poll on Patreon:

The result of the pregnancy poll shows many of you like it, so I will take that into account when the time comes, while making it optional for those who don't like it. The choice to either enable or disable pregnancy will come already in v0.4, as a lot of the story part of v0.4 will revolve around this issue (whether you opt in to pregnancy or not), as part of the continuation of the "Spreading the seed" quest that started in v0.3.
Note that while you will make the choice of enabling or disabling pregnancy in v0.4, actual pregnancy content will not come in v0.4 and it may be a long time before it happens, depending on how I decide to move things forward in the story time-wise, trying to keep it at least somewhat realistic.
Also, if you opt out on pregnancy, don't feel like you're missing out on a huge part of the future game experience. Due to the limitations of nun pregnancy "source material", I never planned on making it a big thing.
