Estrogen question???

Jessica
I asked over in general ttc but got no responses. I'm 33 & TTC my 1st. My doctor recently diagnosed me with polycystic ovaries & I have a very thin uterine lining. He's prescribing me 28 days or estrogen followed by provera to make me get a period. Then clomid if everything goes well. I take maca & vitex daily & asked if I should stop before starting the estrogen. He had never heard of the vitamins & didn't know. What do you ladies think? Should I stop?
