You’re tired, you’re moody, and chocolate suddenly seems like a staple for survival. Your period might be just around the corner. Even if your monthly cycle runs like clockwork, it’s easy to forget when and how hormonal shifts will impact your life and when your period is due to arrive.
You no longer have to rely on your memory and appointment planner to keep you in the know about your body’s schedule. Whether you want to chart your fertility, monitor your moods, or know the second your period is MIA, you can find a period-tracking app to map your month.
