About Hormonology &
Gabrielle Lichterman

Gabrielle Lichterman is leading the growing movement among women to live in sync with their menstrual cycles and know more about all the ways their hormones impact their moods, health and behavior – a movement that began with her groundbreaking book, 28 Days: What Your Cycle Reveals about Your Love Life, Moods and Potential, and her creation of Hormonology.

About Hormonology & Gabrielle Lichterman

“Most girls and women aren’t taught about how the ups and downs of hormones in their monthly cycles will be impacting their moods, energy, romantic feelings, spending habits, sleep quality, food cravings and health all cycle long. This can lead to years of self-doubt, worry, frustration and confusion about why they feel or behave a certain way or why health issues worsen or improve for no apparent reason. So, my mission is to share hormone information with others through Hormonology to ensure that all future generations of girls and women have this knowledge starting with their very first cycle.”

Founder & Inventor of Hormonology

The Hormone Horoscope is the most popular Hormonology tool for learning how your hormones impact your moods, health and behavior all cycle long.

Today’s Hormone Horoscope

My Hormonology

Week 1: Day 1 (first day of period) to Day 7

Estrogen rises: As your Week 1 goes on, you’re likely connecting more with others both verbally and physically. That’s because rising estrogen is making you chatty and willing to strike up a conversation with just about anyone and it has you closing in on people’s personal space and doling out more arm touches, back pats, hugs and kisses. Find out more by downloading the Hormone Horoscope App.

Week 2: Day 8 to ovulation (Day 14 in a 28-day cycle)

Estrogen and testosterone rise till they peak: Your friends, partner or kids could possibly be (and how do I say this politely?) a little embarrassed by you today. The reason? High estrogen and testosterone are amping up your desire for really silly fun as well as your confidence. Together these hormonal effects have you more easily spurred to do something that can make others around you want to hide their face, such as singing out loud in the supermarket aisles, dancing the rumba in the farmer’s market and dressing up early for Halloween to give your costume a test run–and not caring if (okay, when) anyone notices. Find out more by downloading the Hormone Horoscope App.

Week 3: Starts day after ovulation & lasts 8 days

Estrogen and testosterone drop for half the week, then estrogen rises again; progesterone rises throughout: You may take time to clean, organize or do a home improvement project this week. As progesterone rises, it has you putting an emphasis on improving your personal space by making it prettier or more useful. Find out more by downloading the Hormone Horoscope App.

Week 4: Final 6 days of your cycle

Estrogen and progesterone plunge: Try to keep your eyes peeled for opportunities today. Plunging estrogen gives you the tendency to see the negative side of things and think cynically, which could lead you to turn down the chance to meet someone new or do something different. Thing is, research shows that opening yourself to new experiences is one of the top ways people hear about plum jobs, eligible singles and other great opportunities.

“A couple years ago, I started dating this guy and he wanted to move in but I wasn’t quite ready for this step even though I was head over heels about him. I had a big decision to make and, knowing how much Hormonology has helped me in the past, I reached out to Gabrielle. She replied right away and her kindness, generosity, and wealth of information about what happens during my cycle was invaluable. Per her advice, I logged in my calendar that during Days 18-22 of my cycle, I should give this big decision my attention. Thanks to Gabrielle, I knew that this part of my Week 3 allows me to see everything: good AND bad. I can weigh it all and make my decision with a clear viewpoint. Having Gabrielle’s help and insight made me feel smarter about my position and wiser about consequences and potential pitfalls.

Fast-forward to today; we’ve been married nearly a year and loving every moment!

Hormonology has helped us communicate better, too. I can tell him when I’m in a specific week of my cycle and what to expect my reactions to things to be. I’ve never had this kind of open communication in a relationship before and it’s so empowering!”

Mickie C, Philadelphia, Pennsylvania

“Until reading Gabrielle’s book, 28 Days, I never had any idea of the effects of my hormones! I knew they affected me around my cycle, but I never recognized the pattern to my monthly mood swings and energy levels.

I became able to predict and plan for different days and my (now) husband learned basically what to expect and why.

After my periods became irregular and my cramps were out of control, I consulted with Gabrielle for more in-depth information.

She has clearly done an astounding amount of research and was able to talk to me in a way I could understand, just as comfortably as talking to a friend.

She explained more to me about how to recognize my ovulationscope results to know what to expect when with my longer, sometimes unpredictable, cycles and completely surprised me with the fact that I could use my TENS unit (a saving grace for my back issues) for cramps!!! With her advice on placement of the electrodes, I experienced amazing relief on my most crippling days and a complete solution on lesser days.

I think doctors need to take a page out of her book, so to speak! I will never hesitate to consult with her, along with my gynecologist, with any issue involving my hormones.”

Tanya H, Philadelphia, Pennsylvania

“I reached out to Gabrielle in regards to a drastically sudden change in my cycle to which she calmed my nerves with her infinite wisdom. She shared with me that stress, illness, or medication could have been the culprit. This exchange left me with the knowledge to be mindful all throughout my cycle so that the effects of stress no longer manipulate my natural rhythm.

Hormonology has helped me tremendously along my journey. For the past three years, I have referenced it religiously and can now see these fluctuations within myself more consciously. Hormonology has helped me to observe these rhythms and act accordingly. A big THANK YOU to Gabrielle for taking the time to do the research on such an elusive yet significant subject. The Hormone Horoscope Pro App is so accurate and helpful, I just send my husband screenshots of my horoscope and he is appreciative to be in the know from week to week. (A+ for helping with communication and event planning!)

Gabrielle’s dedication to Hormonology is helping to empower women like me all over the globe, and for that I applaud her. Planting seeds of knowledge will help future generations acknowledge and embrace their extraordinary cycles.”

Mélisse L, Nutley, New Jersey
“I need all the energy I can get and that’s hard to come by after a mid-cycle hormone crash. Not only is Gabrielle responsible for helping me see this issue in the first place, she was also there for me when I reached out for advice on how to overcome it. I feel like I’ve found someone who has an owners manual for my female body! Nothing can stop me now.”
Jennifer W, Chicago, Illinois
