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: While rising estrogen in your Week 1 and Week 2 can boost your mood and outlook, it can also re-energize you in another way: It can push you to seek justice for a misdeed someone did to you, for instance, you may file a lawsuit against a contractor who didn’t deliver a project you paid for or you may call a manager to complain about lousy service you received. Why? Rising estrogen is boosting your mental and physical energy and lifting your optimism, which gives you the oomph you need to fight a battle while also making you feel like you’ll be the victor.

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: You may find it difficult to sit still for long periods of time or have racing thoughts today. That’s high estrogen’s influence. As the level of this hormone climbs toward its peak in your Week 2, it ratchets up mental and physical energy, which can make you antsy or even a bit anxious.

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: In your Week 2, you likely had a lot of romantic thoughts and fantasized about cuties you were crushing on. In your Week 3, not so much. The combination of rising progesterone and lower levels of estrogen and testosterone dampens romantic feelings, putting crushes on the back-burner.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: You’re likely to be spending on small items that trigger an immediate boost in your mood, like a holiday-themed drink or DVD of a favorite movie you plan to watch. As researchers explain, these mini-splurges help counter negativity caused by plummeting levels of estrogen in your premenstrual week.
