The Ovulation Connection
Ovulation is the key moment in a woman's cycle: the follicle is mature, and the body is flush with hormones. At this point, PMS symptoms usually appear, particularly around the time that progesterone drops sharply.
Progesterone affects the body in several ways, including helping maintain feelings of well-being, relaxing muscles, and helping the body transform food into energy. So when progesterone levels drop one or two weeks before the period starts, headaches, crabbiness, and bloating kick in.
Progesterone, which can be considered the female equivalent of testosterone, has a great many functions in the body, including:
Regulating the thyroid gland
Raising the body’s core temperature
Acting as an anti-inflammatory and regulating immune response
Acting as an antidepressant
Helping the body use fat for energy
Affecting the body’s sodium-to-water balance
Reducing spasm and relaxing smooth muscle
Normalizing blood sugar levels
Helping the body absorb vitamins and minerals
Enhancing the libido
Promoting bone building
