Irregular Periods
Irregular periods are one of the most common reasons patients visit an OB/GYN. While occasional cycle changes are normal, consistently unpredictable periods can signal an underlying condition that deserves professional attention. At Care for Womens Medical Group, our experienced OB/GYN team in Upland, Rancho Cucamonga, Chino Hills, and Eastvale provides compassionate care to help you identify the cause and restore balance to your cycle.
What Counts as an Irregular Period?
A typical menstrual cycle lasts between 21 and 35 days. Anything outside that range, or a major shift from your usual pattern, may be considered irregular.
Types of irregular periods include:
- Amenorrhea: No periods for 3+ months (not due to pregnancy)
- Oligomenorrhea: Infrequent periods (35+ days between cycles)
- Menorrhagia: Heavy or prolonged bleeding
- Polymenorrhea: Periods occurring more frequently than every 21 days
- Spotting or breakthrough bleeding between periods
- Unpredictable cycle lengths from month to month
If your cycle is causing discomfort, unpredictability, or daily disruption, it’s time to schedule an evaluation with your OB/GYN.
Common Causes of Irregular Periods
Irregular menstrual cycles can develop for many reasons—some temporary, others tied to long-term health concerns.
Hormonal Causes:
- Polycystic ovary syndrome (PCOS)
- Thyroid disorders (hypothyroidism or hyperthyroidism)
- Perimenopause
- Elevated prolactin levels
Reproductive Health Conditions:
- Uterine fibroids or polyps
- Endometriosis
- Pelvic inflammatory disease (PID)
- Ovarian cysts
Lifestyle and Medical Factors:
- Stress or significant weight fluctuations
- High or very low body weight
- Eating disorders or excessive exercise
- Certain medications, including hormonal birth control
- Chronic conditions like diabetes or celiac disease
Our providers take a personalized approach to determine the root cause and create a treatment plan that aligns with your goals, whether that’s symptom relief, cycle regulation, or fertility support.
When to See an OB/GYN
You should make an appointment with a Care for Womens Medical Group provider if you experience:
- Periods that are consistently early, late, or skipped
- Bleeding that lasts more than seven days
- Needing to change a pad or tampon every 1–2 hours
- Bleeding between periods or after sex
- Severe cramps, fatigue, or dizziness during your cycle
- Difficulty tracking ovulation or concerns about fertility
Irregular periods can affect not only reproductive health but also mood, energy, and overall well-being.
Diagnosis and Testing
Your OB/GYN will begin with a detailed health history and pelvic exam. Depending on your symptoms, additional tests may include:
- Blood work to assess hormone and thyroid levels
- Pelvic ultrasound to evaluate the uterus and ovaries
- Pap smear or endometrial biopsy, if indicated
- Menstrual tracking or ovulation monitoring
A clear diagnosis is the foundation for improving cycle regularity and long-term reproductive health.
Treatment Options
Treatment varies depending on your diagnosis, reproductive goals, and overall health.
Common treatment approaches include:
- Hormonal birth control: Helps regulate cycles and manage heavy or painful bleeding
- Lifestyle changes: Nutrition support, weight management, and stress reduction
- Thyroid or metabolic therapy: Corrects hormonal imbalances
- Medication for PCOS or insulin resistance
- Minimally invasive surgery: For fibroids, polyps, or other structural concerns
For patients hoping to conceive, our OB/GYNs also offer fertility-focused care, including ovulation support and reproductive counseling.
