Enough supply left for daycare

I started pumping 2 weeks ago and I've only accumulated 11 bags of 2-3 oz of breastmilk. I had to use 2 bags while I was away from baby. I will be pumping while at work but I'm sort of worried that I will only be able to pump one 2-3 oz bottle and I figure he needs about 4-5 bottles/day. I'll be away from him from 6:45 am-5:15 pm. How did you guys keep up with having enough for LO while you were away?

Fenugreek and blessed thistle, goats rue, hops, brewers yeast, sesame seeds, oatmeal, a gallon of water a day.....all will build your supply
