Decrease milk supply after going back to work

Tanikka
I just went back to work a week ago and only have time to pump once during the day.  My milk supply has never been plentiful but I'm still trying to give my 2 mo LO what little breast milk I am making. I was able to get about 4 oz when I haven't breastfed or pumped all day but since starting work I'm only getting about 1.5-2oz with pumping and starting to not feel engorged during the day. Has anyone tried taking fenugreek to help increase milk supply this late into the breastfeeding process ? Just trying to see if it's worth putting up with the smell in order to try to increase my milk supply again even by a little bit 😕
