How To Determine Your Period Cycle

Ive Been Using Contraception Will This Affect My Cycle


This depends on what type of contraception youve been using. If youve been taking the pill, your period may be irregular when you first come off it, so try to give yourself up to 3 months for your natural menstrual cycle to get back to its normal routine.

The first period after stopping the pill is known as a withdrawal bleed. The next one after this is your first natural period.

The contraceptive injection can also affect your cycle. Your periods may change and become irregular, heavier, shorter, lighter or stop altogether. This can carry on for some months after you stop the injections.

If you use the contraceptive implant your fertility will return to normal as soon as it is taken out.

What If My Periods Are Further Apart Than Every 35 Days

Menstruating individuals usually begin having a period between ages 9 and 15. The average person experiences at least four periods during their first year of menstruation.

This number will gradually increase with time, with the average adult having at least nine periods a year. This means that some periods may naturally occur more than 35 days apart.

Occasional lateness may also be caused by:

  • stress
  • hormonal birth control
  • perimenopause

Chronic lateness may be caused by an underlying condition. Polycystic ovary syndrome , for example, can cause:

  • irregular periods
  • excess hair growth on the body
  • unexpected weight gain

Premature ovarian failure may also cause irregular or occasional periods in menstruating individuals under age 40.

Pregnancy is another possibility. If youre sexually active, it may be a good idea to take a home pregnancy test.

If you suspect pregnancy or another underlying condition is to blame, make an appointment with a doctor. They can assess your symptoms and advise you on any next steps.

What Happens In Each Menstrual Cycle

Why should you care about how to calculate menstrual cycle? It matters for many reasons. Some women just want to know when to expect the monthly flow. Others are trying to get pregnant and want to be able to track their ovulation timesthis begins by learning to track periods. Others just want to make sure everything is okay each month.

A menstrual cycle is much more than just a period. There are actually three very distinct phases throughout the month that create the full cycle.

Day 1 to 12: The Follicular Phase

This begins on the day you begin to bleed and continues until the day you ovulate. Certain hormones course through the body and prepare the ovaries to release follicles. One of those follicles will grow rapidly and turn into the ovum or the egg that is released during the ovulatory phase. The follicle secretes estrogen, and that helps build up the lining of the uterus.

Day 13 to 15: The Ovulatory Phase

In this phase, the egg is released into the fallopian tube. Once it is released, there is a 24-48 hour window during which it could be fertilized by male sperm. Cervical mucus increases during this time, to help the sperm swim up to the egg. If the egg is not fertilized, the lining begins to break down and the next phase begins.

Day 16 to 28: The Luteal Phase

How Long Is My Fertility Window

The fertility window has a length of 8 days. The fertility window begins when sperm can theoretically survive within your body long enough to fertilise an egg. The fertility window ends with the maximum lifespan of an egg. As an egg can only survive 1 day outside of the ovaries, the window ends 1 day after ovulation.

Period Length And Perimenopause

How to calculate the length of your menstrual cycle

In the years leading up to menopause, many women experience changes in their period flow and cycle length. This time of transition is called perimenopause. It can last a year or two or several years.

If youre in your 40s or 50s and your periods are suddenly unpredictable, perimenopause may be the reason. But play it safe and ask your doctor about any changes you notice.

What Is Pre Period

Pre period, also known as premenstrual syndrome , is a syndrome that up to 90% of women will experience in their reproductive lives. It is characterised by headaches, mood swings, feeling anxious, irritable or upset, feeling tired or having trouble sleeping, stomach pain, breast tenderness, spotty skin or greasy hair and changes in libido and appetite. The causes are not fully understood, but some doctors think it is linked to changes in hormone levels due to the menstrual cycle.

What Happens During A Menstrual Cycle

The menstrual cycle begins with the first day of bleeding and ends the day before the next menstrual bleeding.

  • There are essentially two halves of the menstrual cycle:
  • The follicular phase aka pre-ovulatory phase, when the follicle develops inside the ovary. The follicular phase can be further divided into the first couple of days when you have your period, followed by the proliferative phase until you ovulate.
  • The luteal phase after ovulation when the corpus luteum develops in the ovary in the area from where the egg was ejected.
  • During the follicular phase, the levels of estrogen start to rise. Estrogen plays an important role in keeping you healthy, especially by helping keep bones strong as you get older. Estrogen also makes the lining of the uterus grow and thicken. This lining of the womb is a place that will nourish the embryo when pregnancy occurs. At the same time, an egg in one of the ovaries starts to mature. On about day 14 of an average 28-day cycle, the egg leaves the ovary. This is called ovulation, and it is at this point that the luteal phase begins.

    If it gets fertilized, the embryo travels through the fallopian tube to the uterus. Hormone levels rise and help prepare the uterine lining for pregnancy. A person with a uterus who ovulates is most likely to get pregnant from having sex during the 4-5 days before or on the day of ovulation. Women with cycles that are shorter or longer than average may ovulate before or after day 14.

    Combined Hormonal Birth Control

    Combined hormonal birth controlâlike the pill, the vaginal ring, or the patchârelease synthetic forms of estrogen and progesterone into your body . When taken as directed, the hormones in these types of birth control prevent your ovaries from preparing and releasing eggs . This stops your bodyâs usual hormonal cycling rhythm, allowing the birth control to regulate the growth and shedding of your uterine lining .

    The bleeding you experience on combined hormonal birth control is not a real period. It is called withdrawal bleeding because it is caused by the withdrawal of hormones during the placebo pills or during the week you donât use your pills, patch, or ring.

    How To Calculate A Menstrual Cycle And Menstrual Period

    The menstrual cycle begins on the first day of your period. In other words, day one of the cycle is the day one of your period, cycle day two is the second day of your period and so on. In general, bleeding is there for three to five days and differs from one woman to another.

    An important point to note is that the cycle begins from the day of your regular bleeding but not spotting. For instance, you started spotting on March 3, but the actual bleeding began a day later. So the first day of your menstrual cycle is March 4. Let’s say you bleed for five days, so, the duration of your menstrual period is five days for the month of March.

    Now, if your next period started on April 2, then your menstrual cycle length is the number of days from March 4 to April 1 , which is 29 days. You should not count the first day of your next period because that day will fall under the next menstrual cycle.

    In general, menstrual period is the number of days you bleed regularly and menstrual cycle is the number of days from first day of your last period to a day before your next period starts. The average length of the menstrual cycle is 28 days but varies from person to person.

    Period Tracking And Pregnancy

    My Fertility Manual

    For many women, a missed period is the first indication of pregnancy. That fact alone is reason enough for sexually active women to keep track of their monthly cycles. Most forms of birth control don’t quite hit the 100% effectiveness mark, and an unplanned pregnancy is the last thing you need.

    In addition to birth control, following the ârhythm methodâ â in which a woman avoids sex during her most fertile days to prevent pregnancy â relies on accurate period tracking.

    On the other end of the spectrum, women trying to conceive can use period tracking to learn when they are the most fertile. This may boost the chances of conception significantly.

    Charting Additional Measures Leads To Greater Success

    Weschler cautions that monitoring only the timing of your menstrual cycle, as some apps do, doesnt give you enough information to accurately predict your future ovulation. The most accurate tracking apps include additional markers like basal body temperature , changes in cervical fluid, ovulatory pain, and the like, she says.

    In addition to period-tracking apps, a good way to monitor ovulation is with an ovulation predictor kit, which you can buy in the drug store. This uses hormones to most accurately tell you when you have ovulated.

    Menstrual Cycle Data Collection

    Physiological data, including daily BBT , cycle by cycle dates of menstruation, and urinary LH test results, were collected prospectively from users of the Natural Cycles app. Participant characteristics including age and BMI were determined through mandatory in-app questions that must be completed during the sign-up process. Users are recommended to measure their temperature on 5 out of 7 days per week as soon as they wake up. They are requested to report whether a temperature measurement may be deviating for reasons such as disrupted sleep or alcohol consumption the night before. The algorithm also identifies deviating temperatures if the value is outside the range 35.037.5°C.

    All users in the study had consented at registration to the use of their data for the purposes of scientific research and could remove their consent at any time. This study was a subanalysis of data collected as part of a wider study protocol that was reviewed and approved by the regional ethics committee .

    What Is The Ovulatory Phase

    The ovulatory phase lasts usually only one to two days. During this phase, the ovum is released from the mature follicle in a process called ovulation because of the increased presence of the hormone LH. Ovulation generally occurs in the 16 to 32 hours following follicle exposure to increased LH levels. The follicle ruptures and releases the ovum into the funnel-shaped end of the fallopian tube. The ovum then makes its way down the tube and into the uterus, hoping to get fertilized along the way.
