Yep, pregnancy will be added later on in the story when it makes sense for the characters, so don't expect it any time soon.
Nope, I've seen a lot of people with that misconception, but software versions aren't actually decimals, even though they look like it. in 0.8.1 the "0" is the major version, the "8" is the minor version, and the "1" is the patch - so it will continue from 0.9.0 to 0.10.0 then 0.11.0 etc. The game isn't even close to finishing.
