For years, my periods were all over the place—sometimes early, sometimes weeks late, and sometimes missing altogether. At first, I blamed it on stress, diet, or just my body being “weird.” But when I started having spotting between cycles, mood swings, and intense cramps, I knew something wasn’t right.

Like many of us, I turned to Google for answers. The results? Everything from PCOS to thyroid issues—which only made me panic more! That’s when I decided to visit Dr. Seon-Hwa Jeong at Second Spring Women.

What Causes Irregular Periods?

Dr. Jeong explained that occasional irregularity is normal, but if it’s happening frequently, there could be underlying causes like:

:small_blue_diamond: Hormonal imbalances (like PCOS or thyroid disorders) :small_blue_diamond: High stress levels or excessive exercise :small_blue_diamond: Birth control side effects :small_blue_diamond: Uterine fibroids or endometriosis :small_blue_diamond: Perimenopause (if you’re in your late 30s or 40s)

When Should You See a Doctor?

Dr. Jeong told me that it’s time to get checked if you have:

:white_check_mark: Periods less than 21 days or more than 35 days apart :white_check_mark: Skipped periods for 3+ months (when not pregnant) :white_check_mark: Heavy bleeding or spotting between cycles :white_check_mark: Painful cramps that interfere with daily life

Unlike other clinics where I felt rushed, Dr. Jeong actually listened. She ran hormone tests, checked for PCOS, and gave me a personalized treatment plan. Turns out, my irregular periods were due to a hormonal imbalance—and with treatment, my cycle became predictable for the first time in years!

I used to brush off my irregular periods as just “part of being a woman,” especially when I was stressed or traveling. But after months of unpredictable cycles—sometimes skipping a month entirely—I decided to seek help. I booked an appointment at Second Spring Women, and Dr. Seon-Hwa Jeong was amazing. She explained that causes can range from hormonal imbalances and PCOS to thyroid issues or lifestyle changes. She ran some tests and helped me understand my cycle better than I ever had before. If your periods are consistently irregular or accompanied by pain or excessive bleeding, definitely don’t wait—see a doctor. Second Spring made the process so easy and respectful.

A few years ago, I started experiencing irregular periods—sometimes skipping months, other times dealing with spotting or unusually heavy cycles. I brushed it off at first, thinking it was just stress. But when it persisted, I decided to visit Second Spring Women Clinic in Seoul, where I met Dr. Seon-Hwa Jeong.

She explained that irregular periods can be caused by hormonal imbalances, PCOS, thyroid issues, stress, or even lifestyle changes. In my case, it turned out to be a combination of PCOS and stress. Dr. Jeong created a personalized treatment plan that included both conventional medicine and herbal therapy, and within a few months, my cycles started to regulate.

If your periods are consistently irregular, don’t wait it out—seek help. I highly recommend Second Spring Women and Dr. Seon-Hwa Jeong for thorough, compassionate care.
