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 along, you become more optimistic due to rising estrogen and more impulsive due to estrogen enhancing testosterone’s effect on you. The result? You’re more prone to making split-second decisions because you’re sure the outcome will be positive, for instance, you may end up coloring your hair, donning a daring outfit, splashing out more money than usual on lottery tickets or spilling a big secret to a friend.

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 get the urge to be naughty, play hooky or ditch someone to hang out with someone else who’s way more fun. Blame for your bad-girl ways goes to high estrogen and testosterone, which encourage you to push the envelope and do things on a whim!

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: You get more satisfaction from reading, taking photos, organizing and doing other solitary activities thanks to rising progesterone, which slows you down and makes you a tad less interested in socializing and chatting.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: You may take something someone says the wrong way or you may dwell on an out-and-out snarky comment someone makes. That’s because plunging estrogen is lowering feel-good brain chemicals, which can make you more sensitive to rude comments.
