At DDs 1 month check, our pedi has us answer a PPD questionaire. Apparently I failed.

I don't feel depressed or anything, just a little overwhelmed. (New baby and a 2 year old). I guess my question is who do I bring this up to..... my OB or my PCP? I was on ativan before I got pregnant for anxiety attacks, and that was prescribed to me by my PCP. I have my 6 week pp check this week with my OB though, so I thought I would talk to him about it. Any thoughts or advice would be appreciated. I would really like to make sure I take care of myself ASAP. Thanks ladies!
