Another great thing about this book is that I can take advantage of the "good" hormonal days, when estrogen is high or rising, to make them even better. We are taught that during our periods, this is a bad time of
the month where we will be cranky and miserable. Certainly this can be the case for some, but "28 Days" was the first book I've read that actually informed me that menstruation days are those in which estrogen is rising each day, and that it will improve your mood until ovulation - Gabrielle reminds us that the first day of our period is a day to celebrate two weeks of feeling better, or at least the possibility if there aren't any other medical problems you are dealing with. She offers a lot of science-backed advice on how to improve your mood on these days so that you can take advantage of rising estrogen, and when to see a doctor if you're dealing with certain issues. She also helps us look for all the positive aspects of our premenstrual weeks that we can take advantage of to make them more pleasant.
I'd recommend this to anyone with a regular menstrual cycle - it truly is a life-enhancing tool!

I especially like that this book is truly like a horoscope. You can read it every day and see WHY you may be feeling the way you feel. I leave it on my nightstand and have gotten in the habit of reading it every night. I like knowing how I may be feeling the next day. I think this is a game-changer for all people with periods and their partners!! BUY IT! :)

The one thing that I'd like to note about the Hormone Horoscope app and the book "28 days" is that the Hormone Horoscope app has a calendar, but the book doesn't have that feature. Why is this worth noting? Well, because, with the app you can see how your Cycle Days lines up with the days of the week, but you can't with the book. For instance, if I use the app to plan to take a day off work for my period (one of the perks of being self-employed), thats easy. I just check and see if my period lands on a weekday or weekend. If it lands on a week day then I might just take off early. If it is on a weekend I can note that. But, if I use the book I have no way of telling if my period is going to be on a week day or weekend. I'd have to go refer to the app. It is an extra step, but something to be aware of if you intend to use the book for planning purposes. I still love the book and recommend reading it to further your own understanding of your hormonal shifts. Once you get that down, the book can be a reference guide (it is chock full of research all in one place) you look at when things are off kilter or you need a refresher.
