Knowing yourself
Why we made Barkat

Knowing yourself: noticing your patterns and naming your feelings
How noticing your moods, energy and sleep across your cycle gives you more choice, and what research says about putting feelings into words.
Your cycle
Why your menstrual cycle is a vital sign
ACOG calls the menstrual cycle a vital sign for teens. Here is what that means, what a typical cycle looks like, and how tracking helps you and your doctor.
The four phases of your menstrual cycle
What happens with your hormones in the menstrual, follicular, ovulation and luteal phases, and how energy, mood, sleep and appetite can shift.
What counts as a normal menstrual cycle length
Adult cycles commonly run 21 to 35 days and teen cycles can be longer. Learn why length varies, why the luteal phase is steadier, and when to see a doctor.
Fertility signs
Understanding your fertility: the fertile window, signs and age
How the fertile window works, the body signs that mark it, what age does and doesn't mean, and when to see a doctor if you are trying to get pregnant.
How to chart your basal body temperature (BBT)
How to take your waking temperature, why it rises after ovulation, how the 3-over-6 rule and coverline work, and what a BBT chart can't tell you.
Cervical fluid: what changes across your cycle and why
What cervical fluid is, how it shifts from dry to sticky, creamy, watery and egg-white across your cycle, and how to check your cervix position too.
