We’ve all had those days when we woke up feeling flawless, but there are other days when we don’t even want to look in the mirror.

What’s the deal with that? Apparently, your hormones play a major factor in the way you look and feel — especially during certain phases of your menstrual cycle, studies show that women have “good face days” when certain hormones are at play.

Let’s break down the steps of the menstrual cycle and how it affects you.

Phase 1: Bleeding Phase. Phase one begins the first day of your period and usually lasts anywhere between three to five days. During this phase, the hormone progesterone significantly drops, causing the shedding of your uterine lining. While on your period, your energy levels at the lowest, so try and relax as much as you can.

Phase 2: Follicular Phase. Once your period ends, the follicular phase begins and lasts anywhere from seven to 13 days. Follicle Stimulating Hormone (FSH) is released during this phase, and this hormone is in charge of getting your ovaries ready for maturation. In this phase, the pituitary gland also releases Luteinizing Hormone (LH), which leads to ovulation.

Phase 3: Ovulation. Lasting about three days total, this is when your estrogen and testosterone levels are at their highest, and it’s also your most fertile time. The spike in estrogen gives you glowing skin and a more symmetrical face shape. Men are most drawn to women during this phase without even knowing it, due to released pheromones, and women to men also. A woman’s sense of smell is heightened, and energy levels are usually highest during this time — a good time to get a FabFitFun TV workout in. Try and plan important events during this time, as you’ll be radiating confidence!

Phase 4: Luteal Phase. The luteal phase lasts about 14 days, and estrogen and testosterone begin to decline, while progesterone starts to rise. Ever feel hot and bothered right before your period hits? That’s because progesterone is a heat-inducing hormone, and it raises body temperature during the last few days of this phase. During the second half of the luteal phase is when PMS commences, which will cause you to crave certain junk foods, create excess bloating, and increase your mood swings.
