I take fertilaid, fertileCM, fertilitea, maca root, spirulina, B6, and royal jelly. I've also been eating healthier. In one month of all this my progesterone went from 2.4 to 6.9, my chart looks better, my O wasn't as delayed, and my lp went from 10/11 days to 12. So, I'm thinking all those things are making a difference. Good luck!
