Great for TTC
I was told to take this while in my fertile window it does help with cm but it just made me feel funny taking it for multiple days. I’m not really a medicine person I try to take herbal remedies instead so maybe that’s why. I didn’t end up pregnant but I know people who did

Doesn't work well
I bought a package of seven pills, but after eating I felt like phlegm was still in my lungs.
