Natural alternatives to Chlomid

Anna
So after TTC and charting since Aug-15, I got a confirmation from my doctor today that I am not ovulating regularly. She wanted to put me on Chlomid right away, but I prefer trying natural remedies before going down the medicinal route. I will turn 35 in June and I have no kids. 
I plan to take Vitex and Maca for three months and take blood tests on day 24 of my cycle to see if my progesterone spiked. I am also on a good fertility diet, exercise regularly, sleep well, don't smoke and drink green smoothies and green tea. 
Any other ideas? Thanks!
