Katie I would order the dom. Are you open to trying the protocol for 30 days? You could go on it and nurse baby with your lact-aid while you are taking the bcp and dom.
I had 2 bio children whom I had nursed but it had been 11 years when my adopted DD was born. I tried just herbs and a lact-aid system, it went okay (we were at the breast at least), I added dom and things picked up some. I finally went on the accelerated protocol and we could totally give up the nurser. If I had it to do over again I would go straight on the protocol.
