M.T.
I've only been familiar with its use in late pregnancy, to tone and condition the uterus. With my last baby (12 years ago), my midwives had me start drinking a cup in the last trimester, and it gradually increased to 3 cups a day at the end. I also drank it at the end of my first pregnancy, 16 years ago. I've heard nothing about its usefulness when you are ttc.
