A missed period here or there might not seem like a big deal. However, when your menstrual cycle becomes unpredictable, it may be time to talk with your OB-GYN. At Complete Healthcare in Richland, WA, we help women of all ages understand what’s normal, what’s not, and when further evaluation is needed.

What Counts as an Irregular Period?

The average menstrual cycle lasts about 21–35 days, with bleeding that lasts 2–7 days.

Irregular periods include cycles that are:

Too short (less than 21 days)
Too long (more than 35 days)
Unpredictable (missed or widely varying from month to month)
Excessively heavy or light
Accompanied by severe pain or clotting

Occasional irregularities are common, but persistent changes may indicate a hormonal imbalance or underlying condition that needs attention.

Common Causes of Irregular Periods

Irregular periods can happen for many reasons. Some of the most common include:

1. Polycystic Ovary Syndrome (PCOS)

PCOS is a hormonal disorder that can cause missed periods, acne, and excessive hair growth due to high androgen levels.

2. Perimenopause

As estrogen and progesterone levels shift in your 40s, periods can become erratic before stopping entirely at menopause.

3. Thyroid Disorders

Both underactive (hypothyroidism) and overactive (hyperthyroidism) thyroid function can disrupt your cycle.

4. Stress and Lifestyle Changes

Emotional stress, extreme exercise, travel, or sudden weight changes can all impact ovulation and menstruation.

5. Birth Control or Medication Changes

Starting, stopping, or changing hormonal birth control can affect bleeding patterns temporarily or long-term.

When to See a Gynecologist

Contact your OB-GYN if you experience:

More than three missed periods in a row (not due to pregnancy)
Periods that come more often than every 21 days or less than every 35
Very heavy bleeding (soaking through pads hourly)
Severe pelvic pain or cramping with your period
Bleeding between periods or after sex
Postmenopausal bleeding (any bleeding after menopause)

These symptoms could indicate a hormonal issue, uterine fibroids, endometriosis, thyroid imbalance, or other gynecologic concerns that benefit from early diagnosis and treatment.

How We Can Help at Complete Healthcare

When you visit Complete Healthcare for irregular periods, we take a comprehensive approach:

Detailed menstrual history and symptom review
Pelvic exam and ultrasound, if indicated
Bloodwork to assess hormone levels, thyroid function, or anemia
Individualized treatment based on your diagnosis and goals

We may recommend lifestyle changes, non-hormonal supplements, hormonal birth control, or other therapies depending on your specific needs.

Why Regular Cycles Matter

Your menstrual cycle is a reflection of your hormonal and reproductive health. Ignoring irregularities may delay diagnosis of conditions like PCOS, thyroid disease, or uterine abnormalities. With the right care, many women can restore normal cycles and feel physically and emotionally better.

Understanding Your Body

It's essential to understand your body and its signals. Irregular periods can be your body's way of communicating that something is off. By paying attention to these signals, you can take proactive steps toward better health.

The Importance of Open Communication

When you visit your healthcare provider, be open about your symptoms. Discuss any changes you've noticed, even if they seem minor. This information can help your doctor make an accurate diagnosis.

Empowering Yourself with Knowledge

Educating yourself about menstrual health can empower you to make informed decisions. Understanding what constitutes a normal cycle can help you recognize when something is amiss.

Seeking Support from Others

Sometimes, discussing your experiences with friends or family can provide comfort and insight. You may find that others have faced similar challenges, and sharing can help alleviate feelings of isolation.
