CBD for ppd?

I think I'm developing postpartum depression. I don't feel like it's full blown yet, but it's already enough that I'm not myself and I don't like it. I live in PA so it's not legal to smoke pot, and I don't want to be high all the time anyway. I'm looking into CBD as a natural alternative to perscriptions. Does anyone take CBD? What form works best for you? What dosage? I had low dose gummies and oil when I was pregnant to help with nausea so I'm not a total newb, just not sure for this situation. Money is tight so that is a concern, but I don't have health insurance to pay for meds anyway. Also, not breastfeeding if that makes a difference.
