What Are The Reasons For Missing Your Period

When Do You Get Your Period On Birth Control Pills

Missed your period? Here are some reasons why

Once youve started your seven-day break from the pill each month, youll usually start to bleed two to four days into the pill-free week. This varies for each person, but birth control tends to make cycles very regular. That means that after a few months on the pill, youll probably find that your period usually starts on the same day of that week every month.

Youll probably be getting your withdrawal bleeding every 28 days, but even after your body has gotten used to the pill, you can still experience late “periods” on birth control.

Keep in mind that your birth control only works effectively if you take it correctly. If youve forgotten to take three or more non-placebo pills, you could experience withdrawal bleeding before your seven-day break is scheduled. This would mean that you are no longer protected for the month and that you need to use a backup method of birth control and start a new pack.

When To Call Your Healthcare Provider

Missing a period every once in a while is usually not cause for concern. That said, you should see a healthcare provider if you miss more than one period, or your missed period is accompanied by new or unusual symptoms.

Seek medical attention right away if you also experience any of the following:

  • New or worsening headaches

Referral To A Specialist

If your GP thinks a medical condition might have caused your periods to stop, they may refer you to a specialist.

Depending on what your GP thinks is causing the problem, you may be referred to:

  • a gynaecologist â a specialist in treating conditions affecting the female reproductive system
  • an endocrinologist â a specialist in treating hormonal conditions

You may have a gynaecological examination and various tests, including:

  • blood tests â to see if you have abnormal levels of certain hormones
  • an ultrasound scan, CT scan or MRI scan â to identify any problems with your reproductive system or the pituitary gland in your brain

How Late Can A Period Be Without Being Pregnant

However, so long as you are not pregnant, your period can be infrequent with the time between each period varying, the number of days for bleeding varying, and even having a heavy flow or light flow during the period.

Sohow Much Of A Delay In Your Period Is Still Considered Normal

12 Reasons you missed your period other than pregnancy ...

âIf you have one or two irregular periods it is definitely something to pay attention to,â says Sherry Ross, MD, an ob-gyn at Providence Saint Johnâs Health Center in Santa Monica, California. A period is considered late if it hasnât started five or more days after the day you expected it to begin, according to Summit Medical Group. So if your period is, say, 10 days late, definitely take a pregnancy test and check in with your ob-gyn regardless of the results. In general, if your flow has been MIA for a week or more, that’s a sign you should take the test and also check in with your gyno to see what might be going on.

But again, you can miss a period and *not* be pregnant. If there’s no way you’re pregnant and/or your test comes back negative , one of these factors, including all the stress you might be under right now, may be to blame for your late period problems. Then, your next step is definitely calling your doc so they can help you suss out the best solution or treatment for your situation.

How Late Is Too Late For Your Period

Because menstrual cycles can vary from person to person, Lincoln recommends you track your cycle to figure out what is normal for you.

If you typically have regular cycles and your period is late, you may want to take a pregnancy test. “The best time to test is to wait until you’ve missed your expected period, but some can detect pregnancy a few days earlier than this. If you got a negative early test and your period still doesn’t show up, you can test again,” Lincoln says.

If you’re not pregnant, and you still aren’t getting your period, you should see your doctor. “The missing period is a symptom, not a diagnosis, so it’s important to figure out why it isn’t there,” Lincoln says.

Why Am I Not Getting My Period At All

The medical term for absent periods is amenorrhea, and is considered to occur when a woman who has previously had normal periods stops menstruating for six months or more. Many of the causes of amenorrhea are the same as those for a skipped period. Your period can be absent for a number of reasons:


The most common reason to not get your period is because you are pregnant. A home pregnancy test can quickly tell you if that is the reason.


Most women stop getting their periods in their late 40s or early 50s. The average age is 51 years old.


If you breastfeed frequently, including at night-time, you may not get a period for many months. Be aware that you will ovulate prior to getting your period back, so birth control is important if you are not ready to be pregnant again.


While a sudden stressful life event can result in a single missed period, ongoing, high level stress and anxiety can cause your period to stop altogether. Managing stress though self-care, counselling, changing your life circumstances, medication, or other strategies can help you return to having normal periods.

Weight loss

Ongoing, dramatic weight loss, from low intake, excessive exercise, gastric bypass surgery, or eating disorders such as anorexia or bulimia can stop your period. This happens because the hormones required for ovulation are not produced.

Reasons For Missed Or Irregular Periods

By Jillian Levy, CHHC

May 16, 2017

Abnormal menstrual cycles can be a complicated issue to fix, since womens hormones are impacted by a number of different factors and bodily systems. According to a 2011 report about absent periods published in the Journal of Clinical Endocrinology and Metabolism, frequently missed periods over an extended period of time is a relatively common condition that is present in up to 5 percent of adult women at any time. Meanwhile, many more women experience irregular periods on and off throughout their reproductive years.

The hypothalamus in the brain, pituitary, ovarian, adrenal and thyroid glands all help regulate menstruation and balance hormones naturally, so its important to pay attention to widespread lifestyle habits that can be negatively affecting hormonal levels.

You Just Used Emergency Contraception

What can cause a missed period? – Dr. Shefali Tyagi

It might seem a little strange that an emergency contraceptive could cause a missed period, but its totally normal according to Twogood. An emergency contraceptive, like Plan B, contains the progestin hormone levonorgestrel, which is also in hormonal birth control. Levonorgestrel prevents ovulation, which can cause menstrual abnormalities. The high concentration of levonorgestrel in emergency contraceptives can alter your bodys natural hormonal cycles, which can lead to a delayed or missed period.

Why Did I Miss A Period

Missing a period is not uncommon, and most of the time, it is not a cause for concern. Some of the reasons you might miss a period include:

Normal lifecycle changes

There are a number of changes that happen in the female lifecycle that can result in a skipped period. All of these are normal reasons to miss a period and are not cause for concern.

For example:


The most common reason for a missed period is pregnancy. If this is a possibility, take a home pregnancy test to see if this is the cause of your missed period. If you skip a period and then have one the next month at the expected time, its possible that a non-viable pregnancy occurred, and the period is actually an early miscarriage.


Breastfeeding can suppress your period, depending on how frequently you are nursing. You may get a period while breastfeeding, and then not have another one for several months or more, particularly if your baby is nursing exclusively. You can ovulate before you get your period, so its important to use birth control during this time, if you dont want to get pregnant.


A skipped period may be a sign that you are entering menopause and your periods are beginning to become less regular, especially if you are experiencing other symptoms of menopause . If you are 45 or older, there is a good chance this is the cause of a missed period.


Weight loss

Birth control

Hormonal changes


Changes With Your Pill And Other Contraceptives

Kirkham says women who begin a new routine of a birth control pill or IUD may experience normal changes in their period flow.

Sometimes you have to go on the pill to regulate the period. If you go off, you go back to the original problem.

Other reasons women may miss their periods can include taking certain anti-depressant medication, being obese or having a benign tumour called prolactinoma, which is quite rare. Kirkham says the best thing women can do is to alert their health-care provider as soon as they notice changes.

    The Dangers Of Irregular Periods And Missing Your Period

    In women with a regular cycle, normal ovary functioning releases one egg about every 2528 days. Although the average time between periods varies depending on the woman, especially during puberty and the perimenopause periods, most women will have their periods once monthly when theyre in good health.

    When a woman stops getting her period which is called amenorrhea its a solid indication that something isnt right. Primary amenorrhea is when a young woman never got her period to begin with during puberty, while secondary amenorrhea is when a woman has had her period in the past but stops getting her monthly period for three or more months.

    Having a regular, moderately pain-free period each month is a good indication that hormones are in balance and the reproductive system is working properly. The opposite is also true: Irregular periods, missed periods, or very painful and intense PMS symptoms are a sign that levels of one of more hormones are either lacking or are too high. Whether its an underlying health condition, chronic stress levels, a poor diet, too much exercise or low body weight, frequently missed periods when youre sure you arent pregnant that is are not something to ignore.

    In the case of secondary amenorrhea, according to expert Nicola Rinaldi, Ph.D, There are five factors that usually play into hypothalamic amenorrhea : restricted eating, exercise, low weight /BMI /body fat, stress and genetics.
