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
This weekend’s Hormone Horoscope: During the first half of your Week 1, you may have a few foggy-headed moments where you forget where your keys are or can’t remember which month of the year we’re in. That’s because estrogen starts off at rock-bottom on Day 1 and is still relatively low as it begins its slow climb upward. However, by the second half of your Week 1, estrogen will have risen to a point where you’re noticing your memory is far sharper and all the right facts, names, addresses and words come tumbling easily out of your mouth!

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
This weekend’s Hormone Horoscope: Careful with your cash flow, Week 2 gal: Once you start spending, it’s like breaking a dam–your high impulsive testosterone could have you splashing out money in a whirlwind shopping spree!

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
This weekend’s Hormone Horoscope: As your Week 3 goes on and progesterone climbs higher and higher, you may notice it’s easier to trigger a bit of sadness in you, say, when thinking of a beloved pet who passed away or watching a heart-wrenching news story on TV. That’s because progesterone is a hormone that can make you more susceptible to experiencing the blues, which ups the likelihood of you becoming misty-eyed at particularly sad moments.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
This weekend’s Hormone Horoscope: You may worry that a chronic pain or health problem you’re having–like back aches, digestive disorders or migraines–is worsening. What may really be happening is that plunging estrogen is making symptoms more pronounced or more frequent than in the past few weeks. If this is the case with you, you might want to speak with your health care provider about cyclical changes in your symptoms tied to your menstrual cycle. She may be able to customize your treatment that makes your premenstrual Week 4 more comfortable.
