Is anyone using vitex?

I have heard mixed reviews about vitex ? Has anyone used it? Had success? We have been trying for two years so feel like I need some help as 'wait and see' approach is driving me mad . Obviously something is wrong but no idea what,. Drs been pretty useless -I'm waiting for scans but need to feel like I'm doing something in the mean time so,maybe vitex........ Or other natural remedies?????
