The one thing you should know about first-calf heifers is this: They're predictably unpredictable. In other words, a heifer can bag up at any time, from a few weeks before birth to immediately after she dropped a calf. Usually most females will bag up a few days before parturition, but it's a bit more shady when you're dealing with first-calvers.

Whenever and after she calves, which is usually at around 24 months of age.
How does heifer make a difference in the world?
A heifer grows into a cow that produces milk and becomes a mom to new calves which grow themselves and start to create a population. Of course she cannot do this by herself without a bull!

We have a pregnant 2yr old Dexter cow My husband noticed yesterday that she has milk how long before she calves?
This is a pretty unreliable means of telling when a cow will start to calve, or even especially a first-calver, which I assume is the case with this two-year-old "cow" of yours! (At this age she's still called a heifer, by the way.) A heifer can bag up and have really full teats and she'll still not drop a calf until a week or three later. And what's even more interesting is that a heifer can even NOT be bagging up real tight until AFTER the calf hits the ground! So, with that I would really look at her "girly" parts (being the vulva, especially) to truly tell if and when she's close to calving. As mentioned in the related question below, her vulva should be loose, floppy, even swollen looking, and have a clear, non-sticky discharge. The tail head will have sunken down, the belly will have dropped, and the thurls will have sunken in. If she's got a loose and floppy vulva, she will be close to calving in around 24 to 48 hours. So, please see the related question below for more details.
How long can a heifer be in labor?
Heifers don't lactate prior to their first calf. However, they may start lactating several weeks before giving birth, but they aren't lactating like a mature cow does.
How old can a heifer be when she reaches puberty or experiences her first heat cycle?
This depends on the breeding of that heifer. Some heifers that are genetically early maturing or have high fertility will start to experience puberty at around 5 to 6 months of age. Others that are more later maturing or have low fertility won't come into her first heat until she's 18 to 20 months of age. No matter when a heifer goes into puberty, she can only be bred after she's had 3 or 4 normal heat cycles, when her weight is at least 60% to 65% of the weight of the mature cow herd or of the average mature cow weight of similar breeding to her, or when she is 15 months of age or older.
