Does the HCG trigger shot cause your follies to grow a little more? I have one that is ready now (17.5 or maybe bigger by now), and a 14 and 13 (this was as of Wednesday. I did another shot of Follistim Wednesday night so probably a little bit bigger). So I am hoping they get big enough and then I ovulate all of them on Saturday. So does the HCG make them grow a little bit more in the ~36-41 hours or is it the Follistim left over in your system that might make them grow a little more?
