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: As your Week 1 goes on, climbing estrogen is prompting your inner flirt to come on out. Even if you don’t realize it, you’re likely initiating more conversations, being more playful, gussying yourself up and/or heading to places where there are more people you can interact with.

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 be tempted to do something super-fun, but that you’re going to really regret, like kissing someone who’s hot but a total jerk (and who happens to not be the person you’re currently dating), drinking a whole bottle of wine (or two or five) or giving yourself bangs (yes, bangs). That’s because high estrogen and testosterone are making you super-impulsive and they’re ratcheting up your optimism, making you overlook any potential pitfalls. The good news? These hormones are also making you less likely to beat yourself up over any mistakes, so if there’s any week of your cycle that’s best to go against your better judgment, it’s Week 2.

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: During the first half of your cycle, rising estrogen had you curious about the world around you. As this hormone dips to a lower level and progesterone rises during the second half of your cycle, your curiosity turns inward. As a result, you may question why you feel a certain way about an issue, wonder how you can better motivate yourself to reach a goal or study other aspects of your personality a little more closely.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: It’s not that you become totally self-centered this week, but your focus is definitely on your comfort and care, for instance, you might change the TV channel to one you like when someone else is watching a show, you may take 10 minutes to readjust a car seat to get it to your liking when riding as a passenger in someone’s car or you might switch on the a/c when everyone else is freezing. But, who can blame you? Plunging estrogen is putting you in a withdrawal-like state that results in down moods and makes you extra sensitive to physical discomforts.
