How do I know when my pig will go into labor?

[Pezzy12]

I have a mini pig (I've posted before about her). She is definitely pregnant, her belly has grown immensely in the last month. The problem is, I have absolutely no idea how far along she is. Her belly is almost to the floor and her vulva is starting to point out more then usual but its not swollen or anything. What are some signs that she will go into labor soon? She hasn't gotten her milk lines yet I don't think , she is a bit hard to feel because she is shy and won't let me touch her for more then a few seconds. Heres a pic below.

How's your pig doing?

sorry for late reply. She is good. Still no piglets but her nipples are a lot bigger, no milk. Belly is still around the same size. Not sure what to think at this point.
