Tried to see, but even making it larger -- it just got a bit too blurry to tell. But the udder looks great! Since she's building such a nice udder, she may be very kind and fill completely before foaling -- but she could definitely go with an udder like that!
A few other pictures would help -- one from the side down at her level, and one from the back showing how baby is laying -- looking for those "slab" sides!
