I have taken it while ttc. I would take it all month long and I stopped when I got a positive hpt. As for if it works, not sure but I have read good things. I am still to early to know if this baby will stick or not, so not sure about the quality of this egg. I really do believe we have some control over egg quality. I have read that if our eggs dna is damaged there is nothing we can do, but they mature over a 3 month process and certain things can help them mature properly and hence help them be good quality eggs. I have also heard green tea and wheat grass are good for egg quality!
