I had a similar problem. I think if this is your first attempt at getting animals to mate, it won't tell you "with calf" or whatever when you inspect the female cow. Babies still plopped out, and once they had given birth the first time, from that point on, all livestock was listed as "with whatever young" within hours of a male and female being in the pen together.
Not sure if its a bug or a feature where you don't get the notification of animals being pregnant until you've actually gotten a baby livestock, but that's been my experience.
