I used to think my irregular periods were just “one of those things” my body did—like how some people have curly hair and others don’t. But over time, I started noticing patterns that didn’t sit right. Some months, my cycle would be 24 days; other times, I’d go 45 days without a period. At first, I chalked it up to stress, but when I also started experiencing fatigue, mood swings, and occasional spotting, I knew something was off.
After some late-night Google spirals (we’ve all been there), I realized that irregular cycles could be caused by a variety of factors:
- Stress and lifestyle changes – Moving cities, switching jobs, or even an intense workout routine can throw things off.
- Hormonal imbalances – Conditions like PCOS (Polycystic Ovary Syndrome) and thyroid disorders can disrupt ovulation.
- Birth control or medications – Some contraceptives, especially hormonal IUDs or pills, can make periods irregular or stop them altogether.
- Perimenopause – If you’re in your late 30s or 40s, fluctuating hormones could be the culprit.
- Underlying health conditions – In some cases, irregular periods can be a sign of endometriosis, uterine fibroids, or other reproductive health issues.
At first, I hesitated to see a doctor, but a close friend convinced me to visit Dr. Seon-Hwa Jeong at Second Spring Women’s Clinic (link here). She’s incredibly knowledgeable and compassionate—she actually listened to my concerns rather than brushing them off as “normal.” She helped me understand my cycle, ran the right tests, and guided me toward a treatment plan that worked for my body.
When should you see a doctor? If your cycles are consistently irregular (shorter than 21 days, longer than 35 days, or unpredictably fluctuating), if you’re experiencing severe cramps, heavy bleeding, or other unusual symptoms, don’t ignore it. Your body is trying to tell you something.
If you’re looking for a specialist who truly understands women’s health, I highly recommend Dr. Jeong at Second Spring Women’s Clinic. You deserve answers—and the right care.
Hope this helps! Feel free to ask if you have any questions

I used to think irregular periods were just part of life. Stress, travel, hormones—everyone seemed to brush it off. But over time, what started as the occasional missed period turned into months of unpredictability. That’s when I realized something more was going on, and I needed help.
Let me share my story because I know so many women are quietly wondering if what they’re experiencing is “normal.”
The Start of the Confusion
In my early 30s, I noticed my cycle would sometimes stretch from the usual 28 days to 45 days… and then down to 21. Some months I’d spot for a week before my period started, other months I wouldn’t have one at all. It was frustrating, confusing, and honestly—it started to affect my mood, energy levels, and confidence in my body.
A friend of mine (a fellow expat in Seoul) recommended I see a specialist, and that’s when I found Dr. Seon-Hwa Jeong at Second Spring Women in Gangnam.
The Real Causes Behind Irregular Cycles
During my consultation, Dr. Jeong explained that irregular cycles can be caused by a variety of things—some more serious than others:
- Polycystic Ovary Syndrome (PCOS) – one of the most common causes
- Thyroid imbalances
- Perimenopause
- Excessive stress or sudden weight changes
- Hormonal imbalances due to lifestyle or genetics
- Uterine fibroids or endometriosis
She ordered hormone testing, an ultrasound, and a thorough history, and to my surprise, I was diagnosed with mild PCOS—a condition that had gone undetected for years.
