Advice

I am TTC and have been for r about 2 years. I have been on clomid for 7 months and no BFP. I also have PCOS so the only thing so far that the clomid has helped with is regulating me. I went to a health food store because I wanted to see about trying fertiwhey or fertitea. While I was there I asked for some assistant and was told to try Maca Root pills or the powder? Has anyone heard of this or used it? Has it helped? She told me that if I start taking the Maca I would have to stop my clomid. I have thought about trying it for a month and see if it helps with my AF as well. I don't want to try something and my AF stop again. Any advice or personal experiences. Maca is all natural.
