    There is so much to know about your period. When should I expect which symptoms? Is spotting normal for me? How long does a period last? If I'm trying to conceive, what do I need to know about my cycle? What days do I have the heaviest flow, and which are lighter? The list goes on.

    A great place to start, whether or not you're a menstrual cup user, is with a period tracker app. Most take the form of applications you download, often for free, on your phone.

    According to the government, most women menstruate every 28 days, though this can vary between 24 and 38 days depending on the person and the month. The average menstruator gets their period for five days, but anywhere between three and eight days may be considered normal.

    More often than not, people experience some irregularity. This can mean having Aunt Flo show up early, late or not at all. It can mean having a light flow one month and a heavier one the next, seemingly to make up for it. Without the data, it can be tough to know why your body is responding the way it is, and when you should seek medical assistance.

    Please remember that we are not doctors. If you have any questions or concerns about your period, please contact your gynecologist.

    What Affects Your Period?

    There are so many factors that affect your flow -- and that your period tracker can help you manage. For starters, a menstruator's cycle changes as they age and can be divided into three stages:

    1. Menarche: The first period, sometimes extended to the few years that someone is menstruating. The average age of menarche is 12 years old, according to a scientific overview of this stage in the menstrual cycle. During the first few years of menstruation, people are prone to more irregular periods as the body may experience hormonal changes. This can mean shorter (less than 20 days) or longer (over 45 days) intervals between cycles, according to a study published by The American College of Obstetricians and Gynecologists.
    2.  Adult: After the first few years, menstruation becomes more normal. This may mean more even intervals between a period and more predictable symptoms. However, there are a variety of factors that may still affect your flow on a monthly basis.
    3. Menopause or Pre-menopause: The time when a woman's menstrual cycle has stopped for 12 months, signaling that she can no longer become pregnant. Both stages may include hot flashes, sleep difficulties and vaginal dryness, which is another great reason to wear a menstrual cup.

    Other factors that can affect your cycle (no matter your age), include dietary changes, exercise, genetics, stress levels, and health. Whether you're trying to manage your symptoms or conceive, your cycle can be a challenge to understand without a period tracker app.
