Postpartum Depression

I haven't been feeling myself for a while now. I just feel an overwhelming sadness all the time. Preganancy was not nice on my body and I hate the way I look. I want to talk to my Dr but not sure which dr. Do I go to my general family Dr or do I call a therapist, I've never dealt with this before. If it's a family dr, I don't really want to say "oh I think I have depression" to the person I call to make an appt with. How do I word it to make an appt or do I word it just like that?
