FTM. Low supply.

I had my baby 9 days ago. Baby would not latch in the hospital. The nurses and I tried many different methods to motivate him to latch but we had no success unfortunately. I even had several appointments at the mother baby clinic where I spent a couple of hours at a time with the nurses working with my baby trying to get him to latch, but still nothing. I have been pumping regularly to try and keep my supply up. Unfortunately, along with my baby not latching I also haven't been able to produce a good milk supply. I'm lucky if I can produce 30ml/1 ounce a day. One of my nurses suggested I try Fenugreek and blessed thistle. Has anyone tried these and had a good result?
