forgot to add, specifically look for a formula called HRT (hormone rejuvenation) it is an extract, one dropperfull a day, and it also has vitex, mexican yam, dandelion, raspberry leaf, blah blah... read this:

there is info on there about what each herb does.

You can use Maca, it's an adaptogen, but a woman should not take Maca during her period. However, I think Maca is better suited to a woman who is actually in or approaching menopause, than for a woman who is still fertile.

As a holistic health advisor, I recommend that women who need to regulate their cycles after a miscarriage or coming off hormonal birth control use an herb called Vitex. The more concentrated extract form is ideal for the first 2-3 months, and then you can go on a normal dose of 400 mg daily once your cycle starts evening out, for maintenance.

Vitex has been used in Europe forever for this purpose. My fave brand is Solaray, as they "green screen" their botanicals for pesticides and herbicides, and they use standardized formulas.

EPO (evening primrose oil) is also good, as the GLA fat it contains assists with hormone regulation. I take both EPO (500 mg) and Vitex every day, as I am in my mid30s and trying to maintain my fertility for as long as possible.
