Is this heifer close?

[DLF]

I have a heifer that we AI'd, but about a week later she seemed to be in standing heat again, so we just put her in with the bull. If she had bred to the AI date she would be due in 3 days and she is looking like she could have a calf anytime. I also felt inside and felt a head and both feet right inside. If she was bred to the bull she would not be due for atleast another 21 days. Could she be due to the AI date?

This being a heifer, it is quite possible she might calve early. Calving early is not only due to being a heifer, it can also be due to breed and size of the heifer.
