PZ, when I first stayed to ttc I took the Blackmore Vitex as per the recommendations of 3 times a day with meals. I also took evening primrose oil from the end of af to the start of O to increase ewcm.

Just a Fyi on vitex, there is conflicting opinions on when to start and stop taking it. I took it from the start of af til O. My herbalist said to take it until preg.

Hope it sorts out your cycle
