You could try counseling if you don't want to do medication
With your hormonal changes depression can happen while pregnant. I would suggest that find ways to relax you. Walks in the park, and being near water normally does it for me. Being around positive things and people should definitely help you as well. Im praying for you!
Try keeping your busy :) go out and look around in stores for your baby. Buy things set her room up. Keep your mind busy :)
