Relactation-pumping

Hey! So I tried breast feeding all 4 of my kids but I felt like I failed. Fast forward to now, I've started my relactation journey. My last child is 1 1/2 years old. I've been pumping all day for almost 2 weeks, taking liquid gold and sunflower lecithin. I'm staying hydrated as well. How long is it going to take to see even droplets come out. Should I consider medication?
