I took maca for 6+ months in my TTC journey, but only as prescribed by a naturopathic physician. It was used to support my adrenal glands, which were not functioning 100%.
Herbs & supplements like maca, vitex, & evening primrose oil are often brought up on forums and websites like these and women are often desperate for anything they think can be helpful. Maca CAN be helpful in the right situation... but it's like saying antibiotics can be helpful - you need to have the problem they are designed to fix and you need to have the dosage and timing that is right for your body. Otherwise, you can actually do damage.
Definitely wait and see how your body handles regulating itself - lots of women can function quite normally through this process. If you have major issues after that, then consider your doctor or natural health practitioner.
