Who should I see...?????

Jess • ✨Married to my knight!! I have two perfect little boys one is 6 the other brand spankin new!!! THIS is happiness!!!!!!
Ok y'all. This is my first experience with civilian doctors. I'm pretty sure I'm developing ppd again and I don't know who I should see about it. Is it my OB/gyn? Do I go to a regular doc? I'm overwhelmed on top of everything too so this is just adding to it all....
Ik it sounds stupid to some but I'm used to going to one place and having everything taken care of by one doc and not 20.
