Wah! So far, preparing to bf liao? Your EDD is in Nov right? Do u know baby's gender already?
I'm not bf expert lah. My BM is also not much as DS is a small drinker. Ivy should be able to provide much better tips as she's doing very well.
Anyway, the bottom line is
<font color="ff0000">SUPPLY = DEMAND</font>
meaning, if you express more, or bb suckle / drink more BM, your supply will increase. But, must make sure you have enough rest and consume enough liquids.</font>
