In my case it took 3 days of ramping up before things really started moving. I started at 3 drops like you, increasing 1 drops with each morning or evening dose. Day 3, my bowels were moving right along, but I wasn't feeling it yet in the way of nausea.
I would remain confident that it will very likely hit you at some early point. You can probably tell first by your stool speeding up a bit, and also gauge by how repulsed you become with the taste and odor. These may be early indicators that you are about to reach your threshold. Probably better to hold or back up a little around that time.
