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: When you can today, take the opportunity to smell flowers you pass in a garden or at the grocery store, sign up for a class or event, take a new route when driving, invite someone different out to lunch or do something else that helps you explore the world and the people, places and stuff in it. As estrogen rises throughout your Week 1, it not only revs your desire to discover and break out of ruts, it boosts levels of brain chemicals that give you more enjoyment when doing so.

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: It’ll be difficult to suppress thoughts of romance and stop yourself from flirting today. Credit for your inner Cupid coming out goes to rising estrogen–which pushes you to find a love match–and high testosterone–which ratchets up your libido, pushing you to make a physical connection.

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: Try to remind yourself to show more emotion when a friend, family member or co-worker tells you something that’s meant to elicit a big response, for instance, get more excited when someone tells you she’s pregnant, show more concern when someone tells you she’s lost her job or act more surprised when someone gives you a huge gift out of the blue. It’s not because you aren’t actually feeling these emotions on the inside. It’s because rising progesterone, a sedating hormone, can make you less animated and emotive on the outside, which can make folks mistakenly believe you don’t care as much as you really do.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: You may get a bit opinionated about people, ideas, TV shows or just a passing car today. That’s because as estrogen plunges, it brings down levels of mood-boosting serotonin with it, so you’re seeing the world with a more critical eye.
