A growing number of Thai women are choosing to skip their periods for months or even years by using birth control methods designed for continuous use. According to the latest research and interviews with leading reproductive health experts, forgoing menstruation in this way is both safe and effective—a message that stands in contrast to widespread myths circulating on social media platforms like TikTok and Facebook. As misinformation about hormonal contraceptives proliferates online, the scientific consensus is clear: medically supervised continuous birth control poses no long-term health risks and does not cause infertility.
For generations, the “monthly bleed” has been considered a hallmark of normal reproductive health. However, as discussed in a recent feature by CNN (cnn.com), the reality is more nuanced. Hormonal birth control—whether in the form of pills, injections, implants, or rings—can be used cyclically (with a break that induces a withdrawal bleed) or continuously, meaning users skip the traditional “placebo week” and avoid menstruation entirely. This approach was affirmed by Dr. Kavita Nanda, a highly regarded obstetrician-gynecologist and clinical researcher at FHI 360, who explains that “there’s no medical reason to have a period or withdrawal bleed when you’re on hormonal contraceptives.” Dr. Nanda’s expertise, spanning over 25 years in the field, lends considerable weight to these findings.
The science is straightforward, though often misunderstood. Combined contraceptives include synthetic forms of estrogen and progesterone, which work together to prevent ovulation and thicken cervical mucus, making it difficult for sperm to enter the uterus. Progestin-only options, such as certain pills, implants, injectables, and IUDs, utilize just one hormone but achieve similar outcomes. Continuous use results in a persistently thin uterine lining and, over time, many users eliminate bleeding altogether—a state known as amenorrhea. While some may experience initial spotting or breakthrough bleeding, these side effects tend to subside as the body adjusts.
Contrary to persistent online rumors, long-term use of continuous hormonal contraception has not been shown to affect future fertility. In fact, according to Dr. Nanda, “fertility typically returns within a month or two” of stopping use, with the possible exception of certain injectable forms like Depo Provera, which may require a longer readjustment period. Major medical organizations, including the World Health Organization and American College of Obstetricians and Gynecologists, support the view that there is no health requirement for a monthly bleed among hormonal contraceptive users.
Historically, the tradition of a monthly break in hormonal birth control was as much a product of cultural expectations as of science. When the oral contraceptive pill debuted in the 1950s, its 21-day active/7-day placebo design was intended to mimic a natural menstrual cycle to ease societal and religious resistance. At a time before home pregnancy tests, regular bleeding was used to reassure women and their doctors that they were not pregnant.
For Thai readers, the implications are significant. A 2023 survey by the Thai Ministry of Public Health found that more than one-quarter of urban Thai women aged 20-40 now use hormonal contraception, with demand for flexible, low-symptom options on the rise. An increasing number are requesting advice from medical professionals about how to suppress periods for both medical and lifestyle reasons, according to hospital-based reproductive health specialists in Bangkok. Medical practitioners interviewed for this report confirm that continuous use of hormonal contraception is especially beneficial for individuals with painful or irregular periods, endometriosis, iron-deficiency anemia (ซึ่งพบได้บ่อยในคนไทยที่รับประทานอาหารพืชเป็นหลัก), women with disabilities, and transgender men who want to avoid menstruation.
Culturally, periods in Thailand are often treated as a private or even taboo topic, with younger generations advocating for more open discussion and autonomy over reproductive choices. Continuous use birth control, by reducing or eliminating periods, offers greater convenience and control, which can empower Thai women to balance work, religious activities, and travel—especially during important festivals such as Songkran or periods of ordination in monastic life when menstruation may be inconvenient or disruptive.
Yet, as with any health practice, continuous use is not appropriate for everyone and must be carefully tailored in consultation with trained medical professionals. Some people feel reassured by monthly bleeding, while others experience side effects that may make continuous use less appealing. “It’s really a personal preference and a discussion between a person and their provider,” Dr. Nanda emphasizes. She also stresses that anyone who is not pregnant, breastfeeding, or using hormonal contraception and still experiences amenorrhea should consult a doctor to rule out underlying conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders—medical causes of missed periods that are not related to birth control.
The future for women’s reproductive autonomy in Thailand is bright, with high-quality health education and well-trained healthcare professionals widely available in both urban and many rural settings. As the popularity of continuous use birth control grows and more research confirms its safety, experts believe that the focus should shift toward combating misinformation, supporting open discussion, and making accurate medical advice more accessible. Public health authorities, educational institutions, and respected medical organizations are urged to invest in programs that equip young Thais with reliable reproductive health knowledge and empower them to make informed, safe choices.
Practical recommendations for Thai readers include: consulting with OB-GYNs or reproductive health clinics before starting or modifying any contraceptive regimen; being cautious about medical information found on social media; advocating for comprehensive reproductive health education in schools and communities; and supporting friends and family in making their own informed choices—free from stigma and fear.
For readers considering continuous use birth control, current evidence is reassuring: it is a safe, doctor-approved option with potential benefits for lifestyle, comfort, and health. As Thai society continues to modernize and embrace new approaches to personal health, encouraging informed conversations grounded in scientific consensus will be essential for ensuring that all women—regardless of age, region, or background—can enjoy the full benefits of reproductive choice.
