Hi, Michelle. I've done some research on this, and unfortunately it's not exactly straightforward. If you look on Wikipedia, you'll find that the volume of a drop isn't well defined. Scientists use measurements varying from 12 to 20 drops per ml, depending on the device and technique used to produce the drop, not to mention the physical properties of the liquid.
So it depends on what's in your HCG solution and what kind of dropper you're using. I've done some tests with my drops and come up with 30 drops per ml, but it could vary depending on where you got your drops and whether there's anything added. (My drops were from HealthyHCG.com.) Using that measurement, it comes out to 36 drops per day or 12 drops three times per day. That's assuming 0.4 ml three times per day as the standard dose.
Here's a way you could test your drops. Get your dropper and measure 10 drops into a spoon. Then get your syringe and pull in the drops to see how many ml it is. If it's not enough to match your desired dose, try putting 15 drops, then 20, etc. Trial and error until you get the right dosage. Or you could try the 10 drops, get the ml equivalent, and do the math from there, but who wants to do math if you can avoid it??? :)
However, there will always be some inconsistency using a dropper. I got 30 drops per ml, but that was an average. After trying it multiple times, the actual numbers varied between 25 and 35 drops per ml, so I just averaged it out. That kind of variation shouldn't really make a huge difference in your dosage, though. It should be enough to trigger the HCG effect either way, and if it's not working or you're worried about it, you could always increase your dosage a little. I wouldn't worry too much about it unless you're worried about running out of drops. You might want to be more precise in that case.
