The problem that most people had was that Sasha's info caused exceptions because of the ovulation code was messed up, to stop getting exceptions when you clicked on her info I had to input some code in the console, that was supplied by others.Pregnancy wasn't programmed in this version (0.16.1) probably, but if you follow the correct route it shows that you had sex during her ovulation days (animation of sperms moving towards the ovulated egg).
Maybe Sasha's first kid will arrive next update, we still don't know (until Megalono writes his plans for next version).
