Depressed all the time

Ana

I’m 18 weeks pregnant and I’ve been constantly sad and depressed for no reason. I’m always thinking this isn’t what I want my life to be. I don’t feel loved. I’ve just been so negative and I don’t know why. I’ve always been a really positive person. I don’t know what to do.

* I’m married and this is my 3rd pregnancy, never have I experienced this.
