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: Your Week 1 could get off to a bumpy start as your body transitions from your premenstrual Week 4 to your menstrual Week 1. For instance, aside from cramps, you may get headaches, diarrhea and/or flare-ups of chronic conditions (such as fibromyalgia or IBS). The good news? As your Week 1 goes on and estrogen levels rise, these symptoms generally ease and you can enjoy the energy-revving, pain-quashing effects that higher levels of this hormone are bringing you.

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: When choosing clothes, ice cream flavors, pillow designs or hair tints, you’re apt to pick more colorful options today. As estrogen and testosterone rise, they boost feel-good brain chemicals that make you prefer happier, more upbeat visuals!

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: Week 3 is when you have to cash the checks that Week 2 you wrote. Meaning? You may be regretting decisions you made last week that you now have to act on this week, like, going through with giving a big speech at an event, remodeling the bathroom yourself or going on a blind date. While you were in Week 2, high hormones had you feeling confident, adventurous, energetic and brave—pretty much the exact opposite of what your hormones have you feeling this week. Oh, you’ll still excel at whatever it is you do. But, you may have to push yourself a little more to do it.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: You may be in a money-saving mindset today as plunging estrogen makes you insecure about your finances. As a result, you may clip coupons, look for deals, resist the lure of impulse buys or consider ways to bring in more income.
