Breast milk production

Hi ladies, any advice on this herb for producing milk. I feel like my milk supply is going down. I EBF. My son is getting enough,but I'm not pumping enough. I worried because I go back to wok in 20days,and I'm not happy about the pumping situation. Did anyone have to consult their doctor before they have it a go? I want to try it, I emailed my doctor,but she's not responding cause she's out on vacation. Any advice would really be appreciative. My son is two months by the way. Will be three months in the 24. I want to breastfeed for 6minths.  I don't know if it will happen, if this pumping situation continues. Thank you in advance ladies 😉
