The good news? We now have medical insight into the phases of the cycle, so understanding your “normal” can help explain any shifts in your mood or energy. With higher levels of both estrogen and testosterone, it’s normal for a woman to feel naturally more positive, body confident, and yearning for a greater and deeper sense of connection and communication. And based on the shifts in hormones, that makes a lot of sense. It’s really helpful to monitor your cycle by using a smartphone application to track the length of your cycle and any other ongoing changes. Your monthly cycle can be thrown off by stress, antibiotics, illness, alcohol consumption, and too much exercise—all of which have the ability to delay ovulation. Passing blood clots during menstruation can be normal, but it does depend on the amount and frequency for each woman. If the clotting is becoming extreme, it’s worth checking with your physician about ruling out anemia and even dysmenorrhea. Mood swings can be hard for you and for those around you, but they don’t have to be the norm. During the luteal phase, when progesterone rises and estrogen dips, mood swings are more common, but if they are severe, see your doctor. A healthy cycle length is all about knowing what’s normal for you and paying attention if or when signs and symptoms change. So listen closely to what your body is asking for; embrace regular stress management techniques; consume high-quality whole foods; and ensure adequate sleep to increase your chances of achieving optimal hormonal balance.
