My HormonologyWhich week are you on in your monthly cycle? Find out what it reveals about what your day has in store:

Week 1
Day 1 (first day of period) to Day 7
Estrogen rises
Today’s Hormone Horoscope: Once you get past the aches and fatigue of your period and your estrogen starts to really climb in your Week 1, your desire to dive into projects climbs with it. Even better, this hormone is boosting your brain skills and mental energy as its level rises, making it easy to get so absorbed in your work, you can be late for appointments, miss out on social events or even skip a meal or two.

Week 2
Day 8 to Day 14 or ovulation (here’s how to tell when you’re ovulating)
Estrogen and testosterone rise till they peak
Today’s Hormone Horoscope: Practically anything can get you thinking about romance and intimacy today. Whether you spot a couple canoodling, a racy ad or simply a plate of cheese fries, it may seem like everything is triggering steamy thoughts. You can point the blame for the distracting daydreams toward high estrogen and testosterone. As these hormones reach their peak in your Week 2, they rev your desire for passion to cycle-long highs.

Week 3
Day 15 (or the day after ovulation) to Day 22
Progesterone rises; estrogen and testosterone drop for half the week, then estrogen rises again
Today’s Hormone Horoscope: Compared to Week 2, the world may seem like a slightly grayer version of itself. Food may not be as delicious. TV shows may not seem as funny. And things that got you excited may not trigger the same enthusiasm now. That’s due to a combination of rising progesterone and lower levels of estrogen, which create brain changes that make experiences feel less intense than they did last week.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: Sure, you probably know that plunging estrogen in your premenstrual Week 4 makes you more prone to pessimism, irritation and down moods as it brings down levels of feel-good chemicals in the brain. Well, now a study in the Academy of Management Journal reveals one key benefit of negativity: It helps you come up with a solution to a sticky problem faster! Turns out, dwelling first on the negative aspects of an issue–for instance, how difficult it is–sends a message to the brain to work harder on solving it, resulting in more creative thinking that helps you find the perfect resolution.
