Mt cat is about 7 weeks pregnant and the other day it looked like her belly had shrunk she hasn't given birth yet as you can still see the kittens moving she keeps panting and that has been for about 2 days now is she going into labor or not help

My cat is doing the same but has dischage but has been like that for the last two days and her temp is under 100 I'm not sure what's going on but she will nest then just lay in the middle of the floor if you get any good answers let me know I'm kind of freaking out here.
