A period that shows up early, late, heavier than usual, or not at all can leave you wondering what’s going on. While occasional changes are common, ongoing irregular periods can sometimes signal an underlying health issue.
The good news is that not every change in your cycle is a reason to worry. Stress, illness, medications, and hormone fluctuations can all affect your period from time to time. Knowing what’s normal and when to see your gynecologist can make it easier to know what to do next.
What Is Considered an Irregular Period?
A normal menstrual cycle usually occurs every 21 to 35 days, with bleeding lasting anywhere from two to seven days. Not every woman follows the exact same schedule, though. Some naturally have slightly shorter or longer cycles.
Examples of irregular periods include:
- Cycles that change significantly from month to month
- Periods that suddenly come much closer together or farther apart
- Unusually heavy bleeding
- Missing periods unexpectedly
- Bleeding that lasts much longer than usual
- Spotting or bleeding between periods
Irregular periods are common during the first few years after menstruation begins. That’s because hormone levels are still changing.
The same thing can happen during perimenopause, the transition leading up to menopause. Outside of those stages, ongoing changes in your cycle are worth discussing with your gynecologist.
What Causes Irregular Periods?
Many things can affect your menstrual cycle. Sometimes the cause is temporary, while other times it may be related to an underlying health condition.
Common causes of irregular periods include:
- Stress
- Illness
- Weight gain or weight loss
- Changes in exercise habits
- Hormonal birth control
- Perimenopause
- Polycystic ovary syndrome (PCOS)
- Thyroid disorders
Even small changes in your routine can affect ovulation and change the timing of your period.
Does a Missed Period Always Mean Pregnancy?
Pregnancy is one of the first things many women think about after a missed period, and it can certainly be the reason. But it’s not the only explanation.
Stress, illness, changes in weight, and changes in exercise habits can all affect ovulation and delay a period. Certain medications may affect menstrual cycles as well, including:
- Birth control methods
- Steroids
- Antidepressants
- Thyroid medications
- Chemotherapy treatments
It’s also common for your period to change after stopping hormonal birth control. For some women, cycles return to normal quickly. For others, it may take several months for hormones and ovulation patterns to settle into a routine again.
Breastfeeding can also affect menstrual cycles after pregnancy.
If there’s any chance you could be pregnant, taking a home pregnancy test is a good first step.
When Should You See a Doctor About Irregular Periods?
Irregular periods are common, and they don’t always mean something is wrong. But in some cases, they can be linked to conditions such as PCOS, thyroid disorders, uterine fibroids, or hormone imbalances.
You should see your gynecologist about irregular periods if you:
- Your periods suddenly become irregular, especially if your cycles were previously predictable
- You miss several periods and aren’t pregnant
- Bleeding becomes unusually heavy
- You pass large blood clots or soak through pads or tampons quickly
- You bleed between periods or notice recurring spotting
- Your cycles are consistently shorter than 21 days or longer than 35 days
- You develop severe pelvic pain
- You bleed after menopause, even if it only happens once
- Your symptoms are affecting your quality of life
Your gynecologist will review your symptoms and medical history. Depending on your situation, an evaluation may include:
- A pelvic exam
- Blood tests to check hormone levels
- Thyroid testing
- Pregnancy testing
- An ultrasound or other imaging test
Getting Answers About Irregular Periods
An occasional change in your cycle isn’t always a cause for concern. Many women experience a late period, a heavier flow, or a shorter cycle from time to time. Stress, illness, travel, and hormonal changes can all play a role.
But if these changes become a pattern, it’s worth getting checked. You should also see your gynecologist if you develop pelvic pain or start bleeding between periods.
