“What are the common causes of irregular menstrual cycles, and how can they impact a woman’s overall health? At what point should someone seek medical attention, and what diagnostic tests or treatments are typically recommended (Second Spring women www.secondspringwomen.com)”?
I used to brush off my irregular periods as “just stress.” For years, my cycle was unpredictable—sometimes 26 days, sometimes 40—and there were months when it wouldn’t show up at all. It wasn’t until I moved to Seoul for work that I realized maybe I should stop chalking it up to lifestyle and actually get it checked out.
That’s when I found Second Spring Women and met Dr. Seon-Hwa Jeong. Honestly, it changed everything for me.
Dr. Jeong’s Insight: Why Periods Go Off Track
At my first consultation, Dr. Jeong sat me down and broke it down in the most understanding, non-judgmental way possible. She explained that irregular menstrual cycles can have a lot of different causes, including:
1. Hormonal Imbalance
Conditions like PCOS (Polycystic Ovary Syndrome) are notorious for disrupting cycles. Dr. Jeong ran some hormone tests to check for this.
2. Thyroid Issues
Both hyper- and hypothyroidism can throw your entire reproductive system off. Apparently, even a slightly underactive thyroid can cause longer cycles.
3. Stress & Lifestyle
Yes, stress does play a role—but it’s not always the sole reason. Dr. Jeong helped me distinguish between mental stress and physical stress (like sudden weight loss or excessive exercise).
4. Perimenopause or Early Menopause
This isn’t just for women in their 40s—some women start showing symptoms earlier. She ruled this out in my case, but it’s more common than I realized.
5. Other Underlying Conditions
Uterine fibroids, endometriosis, or even certain medications can be culprits too. A simple ultrasound helped us get a clearer picture.
When to See a Doctor
Dr. Jeong told me that if your cycle consistently falls outside of 21–35 days, or if you miss multiple periods in a row, it’s time to seek medical advice. Same goes if your periods suddenly become extremely heavy, painful, or accompanied by other symptoms like acne, hair loss, or weight changes.
My Outcome
After some testing, we discovered I had mild PCOS. With a tailored treatment plan (including diet tweaks and hormone regulation), my cycle is now much more regular—and I feel so much more in control of my health.
The best part? Dr. Jeong spoke fluent English, and the clinic was not only modern and efficient, but also designed to make you feel calm and cared for. I felt heard, not rushed—something that’s surprisingly rare, even in women’s health.
Final Thoughts
If your period feels unpredictable or you’re just unsure what’s “normal,” don’t wait too long. I highly recommend Second Spring Women in Seoul. Dr. Seon-Hwa Jeong is one of those rare doctors who makes you feel safe asking all the awkward questions—and she genuinely cares.

I used to think my irregular periods were just stress-related, but when they became more frequent and unpredictable, I decided to seek help.
