Maca and Vitex?

Jamie
I’m finding totally conflicting information and hoping someone can help me clear things up. 
I have irregular cycles. We just hit a year ttc so I’ve decided to try everything the next couple months. I ordered Vitex and Maca root supplements. I had read that they should be taken together. Then I started looking for dosage suggestions and found people saying not to take them together. 
So what’s the reality? Take one? Take both? How much? Help please!
