This girl's on day 160 from the day I have recorded. I am starting to get worried. She doesn't seem to be in distress, but she looks so uncomfortable. She occasionally arches her back, and I think she lost her mucus plug about two weeks ago. I have been thinking she was getting close to kidding about since about two weeks ago, when her personality changed. She is so much friendlier than she was. Her udder and stomach are huge. What do you guys think?
