Irregular Periods at 18: Should I Be Worried?
Hello! I'm an 18-year-old female weighing 78 kg, and I currently don't take any medications or use birth control. For the first time, I've noticed that my menstrual cycles this year have been quite erratic, with the following timeline: - First cycle: January 8 to February 17 (a span of 41 days) - Second cycle: February 18 to March 31 (42 days apart) - Third cycle: April 1 to May 18 (48 days in total) - Now, my current month should have begun on May 19, but as of today, July 5, I'm still waiting for my period. My periods typically last around 4 to 5 days, and I haven't experienced significant pain or other serious symptoms. Could this variation indicate a condition like PCOS or possibly another hormonal imbalance? Is this something I should be anxious about, or is it common for someone my age? Thank you for your help!

Irregular periods can be concerning, especially when they deviate from your normal patterns. However, it's important to recognize that experiencing irregular menstrual cycles is quite common for young women, particularly in the first few years after starting menstruation. Here's what you should know and consider:
Explanation
Your menstrual cycle can be influenced by various factors including hormonal changes, stress, diet, weight, and lifestyle. At 18, your body is still maturing, and hormonal fluctuations are common. That said, the irregularity you're experiencing—cycles lasting 41 to 48 days with a current absence of menstruation (which is now 47 days late)—could be a signal worth investigating, especially if this pattern continues.
While conditions like Polycystic Ovary Syndrome (PCOS) can cause irregular menstrual cycles, many younger women experience a period of irregularity that may resolve over time. Nonetheless, if you are concerned about your symptoms or if they persist, understanding your body’s signals is important.
Next Steps
-
Keep a Menstrual Diary: Document your cycles, noting the start and end dates, along with any additional symptoms (e.g., mood swings, weight changes, acne). This information can be helpful for understanding your patterns and when to seek help.
-
Evaluate Lifestyle Factors: Consider any changes in stress, diet, exercise, or weight that may be contributing to these irregularities. Try to maintain a balanced diet, engage in regular physical activity, and manage stress effectively.
-
Consider Body Weight: If you are overweight (BMI may be a factor), weight loss may help regulate your menstrual cycles. Discuss healthy weight management strategies if this applies to you.
-
Monitor for Other Symptoms: While you haven’t reported significant discomfort, keep an eye out for signs such as excessive hair growth (hirsutism), acne, or changes in mood, which could indicate hormonal imbalances.
-
Make Time for Check-ins: If your periods do not become regular over the next few cycles or if you start experiencing other concerning symptoms, it would be beneficial to initiate a conversation with a healthcare provider. They may evaluate you for conditions like PCOS, thyroid issues, or other hormonal imbalances.
Reassurance
While it’s natural to feel anxious about changes in your body, know that many young women go through periods of irregularity without serious underlying issues. By taking these steps, you can better understand your body and address any concerns if they arise. If you have more questions or need clarification, don't hesitate to reach out again!

Exploring Inositol and CoQ10 for Managing PCOS Symptoms
As a 28-year-old female, I have faced the challenges of polycystic ovary syndrome (PCOS) since my teenage years. Starting from the age of 16, I have dealt with highly irregular menstrual cycles, occurring anywhere from three to eight months apart. My diagnosis has been substantiated through two ultrasounds and blood tests revealing elevated androgen levels. Despite maintaining a healthy diet and leading an active lifestyle—balancing my work as an environmental biologist with gym sessions alongside my husband—I continue to wrestle with weight management. Other symptoms impacting my daily life include significant hair loss, unwanted facial hair, and persistent fatigue. In my journey to manage PCOS, I previously sought counsel from a gynaecologist, who primarily suggested hormonal birth control as the main approach to alleviate my symptoms. Although I adhered to this recommendation for several years, the hormonal changes negatively impacted my mood, leading me to discontinue its use. Another alternative proposed by my gynaecologist involved androgen blockers, but these are not suitable for me since my husband and I plan to start a family in the next two to three years. Recently, my research led me to discover that supplements like Inositol and CoQ10 might effectively combat insulin resistance and lower androgen levels. They are purported to improve various symptoms associated with PCOS, including the regulation of ovulation, all while boasting minimal adverse effects. I am curious about the viability of these supplements as alternatives to hormonal birth control or androgen blockers in managing my PCOS symptoms.
Seeking Clarity on My Spinal Tap Results: A Bit Anxious
I am a 31-year-old woman experiencing a continuous headache for the past four months, accompanied by feelings of nausea and exhaustion. I take Lexapro each day to manage my mental health. I have a history of migraines and headaches, but this recent episode doesn't align with my previous experiences. Here are the findings from my spinal tap: - **Opening Pressure of Cerebrospinal Fluid (CSF)**: 9 cm H₂O - **Presence of Red Blood Cells (RBCs) in CSF**: 2,570 - **Total Protein Level in CSF**: 107 mg/dL - **ACE Level in CSF**: 4.4 - **Other Tests on CSF**: Results were normal. - **Brain MRI and MR Venography**: Both tests yielded normal results. - **Blood Test Results**: Normal results were obtained. Given these results, I'm feeling a bit uneasy and I’m hoping to better understand what they might indicate about my health.
Navigating Health Concerns: A Young Woman's Plight with Chronic Migraines and Stress
To summarize a very complex situation, last spring in 2025 was exceptionally challenging for me. I faced overwhelming stressors, including family deaths, eviction, and my parents splitting up. This turmoil led to chest pains so severe that I had to visit the emergency room because I couldn’t breathe deeply without experiencing intense pain. The doctors attributed the issue to psychological causes, but I continued to suffer from pain and instances of fainting due to the stress, which worsened as yet another family member was diagnosed with cancer. My psychiatrist suggested medication, and I started on Lexapro and Concerta, which improved my condition somewhat, even though I remained fatigued and felt like I was merely surviving. By the end of August, I contracted a severe case of bronchitis that caused me to experience fevers even while doing laundry. It seemed I was verging on pneumonia, prompting the prescription of prednisone and other steroid medications. Thankfully, I began to recover quickly, but soon after, I was plagued by persistent headaches and an overwhelming sense of paranoia that someone was out to get me. After another emergency room visit, the physicians informed me that, although my symptoms—such as fever, intense pain, night sweats, sensitivity to light, ear pressure, and a stiff neck—were alarming, they were likely just severe migraines that should eventually fade. Unfortunately, they didn’t. I returned to urgent care for further treatment, received antibiotics, and was advised to consult a neurologist. While the antibiotics provided some relief, my symptoms intensified. My primary care physician eventually prescribed sumatriptan, a medication intended to alleviate migraine pain, but instead, it exacerbated the headache. For the next two to four weeks, I endured an exceptionally difficult time, facing numerous strange symptoms that felt worthy of immediate attention, yet each visit concluded with a migraine diagnosis and a waiting period for my neurology appointment. My frustrations pushed me to contemplate risky alternatives for relief, but I resisted, feeling utterly hopeless and unable to cope. I sought an ear, nose, and throat specialist to rule out sinus issues, which turned out to be fine. A painful spot under my jaw led me to suspect nerve involvement, and I visited the emergency room again due to experiencing stroke-like symptoms (including mild left arm weakness, extreme headache, and minor speech issues). Sadly, I was again told it was merely a headache, and the IV medications were ineffective. During my annual check-up, my primary care provider was unfamiliar with my ongoing issues but discovered an enlarged lymph node in the lower left side of my neck and a cyst on my thymus after conducting a soft tissue scan. She reassured me that there was no need for concern and suggested waiting for my neurology visit or getting my eyesight checked. Despite my yellower complexion, increasing stiffness, and joint pain, I accepted her recommendation. While I mentally adapted to the chronic pain, which was always present, it affected my ability to concentrate and engage in daily life. I tried consuming plenty of lemon juice and engaging in lymphatic drainage massages, which provided transient relief and halted my yellowing skin. Now, in the present, I've noticed a peculiar, raised red bump on the side of my foot. It’s hard, tender, and smaller than a dime, without any accompanying rash. It has persisted for a couple of weeks without causing pain while walking. Additionally, more lymph nodes in my neck have become swollen, I have experienced difficulty swallowing, and I occasionally choke on air. My lungs feel heavier with a diminished sense of smell, though I don't have the thick mucus typical of a cold. The headaches, however, are reemerging, sharper than before, which is a concerning development. Throughout all of this, my blood pressure has remained within a low yet stable range, and my blood tests and CT scans have shown no significant issues. I haven’t consumed anything excessively that might raise concern, including food or drugs. Am I truly facing a serious health crisis? Should I prioritize getting another appointment, or do I need to rush to urgent care? I'm scheduled to see the neurologist in about a month, and I'm wondering if I should ask my primary care provider for some preliminary tests like blood work or an MRI beforehand. If so, what specific questions should I prepare for my neurology visit? I believe the pain has a genuine physical basis, although my anxiety definitely amplifies the experience.
Concern Regarding Persistent Tongue Bump with White Coating
I am a 24-year-old male, standing at 190 cm tall and weighing 109 kg. For the past five weeks, I've experienced a peculiar issue on my tongue. Specifically, there's a noticeable bump on the right side near the tip, which I believe may have been developing over time, although I'm not entirely sure about that timeline. Recently, I've been troubled by an unusual sensation, including dryness, an odd taste, and a slight decrease in my sense of taste. Additionally, I've observed a white coating that is more pronounced on the aforementioned side of my tongue. The bump in question: - Does not cause any pain. - May have increased slightly in size over the weeks, though I'm uncertain. - Appears smooth with a pink surface, free of bleeding or ulceration. Given that this issue has persisted for over a month, I am feeling quite anxious and am concerned that it may indicate a serious problem. I have no significant medical history, but I confess that my dental hygiene has not been up to par, as I haven’t been brushing regularly. At this moment, I’m also under medication for H. pylori, known as Pylera, but this tongue concern predates my treatment. I am a non-smoker and am reaching out for any insights on this condition. Has anyone experienced something similar? Could this be a sign of irritation, infection, or something benign? I really appreciate any guidance you could provide. Thank you!
Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
