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, you may find that you’re extra-bored doing your usual tasks, say, cooking or studying. The problem is with rising estrogen. As the level of this hormone climbs, it pushes you to go out and have fun rather than stick to your regular chores. 

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: People who need something from you are probably going to love you today. That’s because you’re more likely to say “yes” to favors (even big ones) thanks to high estrogen, which is boosting your mood, and high testosterone, which is making you more impulsive–a combination that can have you agreeing to help someone move, bake cupcakes for a party of 500 or lend out a wad of cash without thinking about the downsides.

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: Try to ignore the numbers on the bathroom scale today. Water retention and constipation triggered by rising progesterone can temporarily add an extra pound or two to your weight, making it seem like a weight-loss plan you’re on has stalled or that the usual meals you eat are somehow adding more to your waistline.

Week 4
Day 23 to the end of cycle
Estrogen and progesterone plunge
Today’s Hormone Horoscope: You may have trouble seeing eye to eye on an issue with someone. The reason? As estrogen plunges, it makes you less flexible in your opinions and more suspicious of other people’s motives, so you’re not as easily persuaded to adopt their point of view.
