wondering if there is pregnancy depression?

Dani • Half team Miller. 1 butterfly baby. 1 rainbow baby to come.
13w ftm and feel sad. Wondering if there is pregnancy depression. My life is good, I have a loving husband. I really have nothing to complain about. So why do I feel so down? I have had lots of pregnancy symptoms that have been uncomfortable but not unbearable. Am I the only one? I cry a lot over the stupidest things but really have nothing to cry over. Any ideas?
