Breastfeeding and pumping

Any of you mums breastfeeding and pumping to make a stash/boost supply? If so how much are you making per day? I'm having to suppliment in the day due to not making enough, hence the pumping too to try and stimulate my body to produce more. Today I made an additional 9.5ozs which has gone in the freezer. Tried fenugreek, fennel and Brewers yeast but they all killed my supply!! So back to good old fashioned supply and demand. My LO is 6weeks
