Agnus Castus has been used very successfully to help regulate hormone levels. But you should also think about a good yeast free multi vitamin, specially formulated for people trying to conceive, and a good oil, like Efamol's Efamarine. These should help regulate your hormones and you should stop the Agnus Castus as soon as you discover that you are pregnant. You may also benefit from some magnesium malate supplements as that will help you relax and sleep, good for reducing stress. You may wish to consider getting some proper guidance by seeing a specialist nutritional therapist.
