Gloomy Mood?

Michaela • 31 years old. Mom of 3
Almost 34 weeks and starting to notice a bout of depression suddenly. I feel blah like I don't want to talk to anyone but my fiance, and I could probably cry for no reason. I really hate the feeling. I didn't have any depression with my first baby. I'm not too worried but I hope it goes away by the time baby comes, I just want to hold her already.
