If I think my milk supply is nearly gone, can I get it back

I haven't pumped or breastfed in over a month...... so is there any chance of getting my milk back? I'm ready to try again but now my milk is gone so😕 I feel like it's too late lol. If I try fenugreek, lactation cookies, mothers milk tea, etc. and try to pump even if there's nothing there, could that bring it back?
