Nursing a 4month old and found out I am 6wks along

I have been having issues with being able to pump enough milk for my daughter while she is at daycare for about a month now. I have tried fenugreek but now that's not a option as I am currently around 6weeks pregnant. Any suggestions on how to boost my supply would be greatly appreciated as my stock pile has only 2-5 packs left and I am quickly becoming a stressed out mess. Thank you in advance
