Is my supply low?

LO is 4 weeks old in two more days I’m ebf but my lactation consultant told me to pump after feedings when she was around 1-2 weeks and a lot of people recommended me not to do that bc I was getting an oversupply. I was pumping 4oz bottles after feedings. Well I stopped bc I did keep getting engorged and it was to painful. So I’ve been pumping occasionally when dad feeds her with a bottle other than that I’m ebf.. I have about 10 bags of 4oz stashed but I’m going back to work soon and I want to have more than that. I’ve been feeding baby and pumping again and I’m only getting 1-2oz 3 if I’m lucky and it’s bothering me.. is that normal amount for 4 weeks old? she’s cluster feeding so she’s on me a lot I would have thought my supply would be up there
