It doesn't say anything about how far along she is. Some moms gain 200 gm some gain 50. It doesn't tell you how many kits she will have or when she's due. Every chin is different. I've got some moms who will gain a bunch in the beginning then nothing and others who gain it all towards the end.
I'm guessing since you are posting thread after thread after thread with breeding questions that this is something you are planning to do. I would suggest, instead, reading through the entire breeding and babies section, as well as the FAQ's regarding kit care, why to breed, etc., and then start asking questions. Then I would put them all in one thread so that you have a place you can reference, rather than 10 or 15 different threads to keep track of.
