Delay in Menstruation After Taking Emergency Contraceptive
Hello, I am a 21-year-old female. My previous menstrual cycle began on May 8, and I generally experience cycles lasting between 30 to 34 days. After taking the emergency contraceptive pill (i-Pill) on May 18, I have not had my period since then. I have conducted several urine pregnancy tests, all yielding negative results, with the most recent test being done not long ago. Although I have experienced some mild premenstrual symptoms, I have not had any menstrual bleeding. Currently, I am about 29 days overdue for my period, and I am not using any forms of birth control aside from the i-Pill. Additionally, I have been feeling somewhat unwell lately—with symptoms including fever and fatigue—which is why I haven’t initiated any treatment to trigger a menstrual cycle yet. I am seeking advice on whether such a delay is typical after using emergency contraception. Should I just wait to see if my period returns, or would it be wise to consider medication or further tests? What steps should I take next?

The delay in your menstruation after taking the emergency contraceptive pill (i-Pill) can be concerning, but it is a relatively common occurrence. Here’s a breakdown of what could be happening and the best steps to take next:
Main Points
- Hormonal Effects of Emergency Contraception: The i-Pill can alter your menstrual cycle, leading to a delay in your period.
- Negative Pregnancy Tests: Consistent negative pregnancy tests are reassuring but not definitive by themselves, especially if your cycle is irregular.
- Accompanying Symptoms: Feeling unwell, with symptoms like fever and fatigue, should be addressed, as they may indicate an underlying issue unrelated to your menstrual cycle.
Explanation
Emergency contraceptive pills like the i-Pill work primarily by delaying ovulation. They can also affect the lining of the uterus and may lead to a delay in your menstrual cycle for several reasons:
- Cycle Disruption: After taking emergency contraception, it’s not unusual for your next period to be delayed, earlier, or heavier than usual.
- Hormonal Fluctuations: The hormones in the i-Pill can lead to variations in your menstrual timing.
Given your negative pregnancy tests, it's likely that you are not pregnant, but your cycle may still be affected by the hormonal changes from the medication.
Next Steps
-
Track Symptoms: Keep a diary of your menstrual symptoms and unwell feelings. Note the exact dates, severity, and any new symptoms. This information can be helpful later.
-
Health Monitoring: Since you feel unwell with symptoms like fever and fatigue, focus on resting and staying hydrated. Pay attention to how these symptoms progress. If they worsen, or if you experience additional concerning symptoms (severe pain, excessive fatigue, etc.), seek medical advice sooner.
-
Wait for Your Period: If your next period doesn’t come in a week or two, it would be wise to consult a healthcare professional. They may recommend further tests or a follow-up evaluation.
-
Consider Birth Control Options: Once your cycle normalizes, consider discussing reliable birth control methods with a healthcare provider to avoid reliance solely on emergency contraception in the future.
Conclusion
A delay in your period after taking emergency contraception can be typical and is usually not a cause for immediate concern, especially with negative pregnancy tests. However, prioritize your overall health, especially with the additional symptoms you’re experiencing. Keep monitoring your symptoms, and don’t hesitate to reach out for help if necessary.

Exploring Endolymphatic Hydrops: Could This Be My Condition?
34 years old / Female Current weight: 165 lbs Navigating the challenges of motherhood In early December 2025, I caught a cold. By mid-December, my right ear felt blocked, but I attributed it to the cold virus. As New Year approached, I experienced another cold, which coincided with an onset of ringing in my ears. Disturbingly, sounds started to seem altered from the affected ear, accompanied by a persistent fullness in that area. Additionally, I noticed twitching of my eye and swelling in the salivary gland on the same side. My primary care physician prescribed a decongestant and Flonase; however, because I am currently breastfeeding, I hesitated to take the medications as directed. On January 27, I was evaluated by an ear, nose, and throat specialist, who requested a hearing assessment the following day. The results indicated that I had sensorineural hearing loss affecting my low-frequency hearing range (250 Hz to 500 Hz). The doctor prescribed a steroid with the hope of addressing the issue promptly. Now on day 10 of steroid treatment, I have experienced significant relief. Remarkably, I've noticed a substantial amount of thick, putty-like mucus clearing from my nasal passages. The pressure in my ear has subsided, and sounds are returning to normal, though I still perceive a slight ringing — possibly just a touch of hearing loss remains. What concerns me is whether ongoing sinus congestion could be the root of these symptoms or if I might genuinely be dealing with endolymphatic hydrops. Notably, I have not experienced any episodes of dizziness. In the evenings, I tend to feel considerable pressure building on the right side of my head, almost as if my sinuses are becoming blocked once more. I would greatly appreciate any insights or advice on this matter, as I find myself in a state of uncertainty regarding my condition.
Experiencing Occasional Hematuria: Seeking Guidance
Greetings, medical professionals. I appreciate your assistance with the following situation. **Patient Overview:** - **Age:** 47 - **Gender:** Male - **Height:** 6 feet - **Weight:** 202 pounds **Symptoms Overview:** Approximately three months ago, I began to observe small traces of blood in my urine. It's a minimal amount, usually just a couple of drops occurring at the end of urination. I do not suffer from any pain, fever, chills, or urinary difficulties. Initially, I suspected that this could be linked to kidney stones or exercise-induced hematuria, as I maintain a rigorous exercise routine spanning two hours daily, seven days a week. My workouts alternate between strength training 3-4 times a week and cardio exercises, including rowing, treadmill use, the elliptical, stair climbing, and jump rope. After several weeks, I also observed tiny tissue-like fragments in my urine, prompting me to consult a doctor, as I suspected a urinary tract infection. Although I have an enlarged prostate, my physician considered it a benign issue, attributing the swelling to the potential chain reaction of a UTI leading to bladder infection and subsequently causing prostate inflammation. **Diagnostic Tests and Outcomes:** I underwent a comprehensive metabolic panel, which included tests for glucose, BUN, creatinine, and various electrolytes. All results fell within normal ranges, with the exception of a low BUN/creatinine ratio (8). Additionally, I received a Creatine Kinase (CPK) test, which returned normal results. A complete blood count (CBC) with differential was conducted, showing all parameters, including WBC, RBC, and hemoglobin, to be normal. Urinalysis reflected negative findings for GLU, BLO, NIT, and LEU. However, it indicated a small amount of bilirubin, a ketone level of 15, a specific gravity of 1.025, a pH of 5.5, and a protein level at 30. Uric acid levels were 8.1, within normal limits, though an inflammatory marker was mildly elevated. A sedimentation rate (Westergren) displayed a slight elevation at 19 (normal range is up to 15). A CT scan of the abdomen and pelvis with contrast yielded several findings: - **Lung Bases:** A few small pulmonary micronodules were noted, but otherwise clear. - **Liver, Spleen, and Pancreas:** All appeared normal without lesions. - **Kidneys:** Normal with no stones or masses. - **GI Tract:** The stomach was mildly distended, but otherwise normal with stool presence noted in the colon. - **Pelvis and Vascular Structures:** Solid organs and vessels appeared normal. - **Other Findings:** Prominent inguinal lymph nodes were potentially reactive, alongside a small left inguinal hernia. **Follow-Up Treatment:** Following these evaluations, my physician prescribed sulfamethoxazole for a duration of 28 days. I adhered to the regimen fully, and while undergoing treatment, all symptoms subsided completely. However, this occurred about a month ago, concluding in late December. **Current Situation:** This evening, after my workout, I noticed the return of blood traces in my urine. While I do not experience pain, I have difficulty with bowel movements, feeling persistently constipated regardless of food intake. This change coincided with a mild tearing sensation during exercise on the adductor machine. Additionally, I have developed a reddish rash on both arms, which had resolved during the antibiotic treatment but has now reappeared. Previously, this rash was effectively treated with prednisone, leaving me unsure if this is connected to my earlier symptoms. **Concerns:** I worry that standard medical tests might overlook a significant issue affecting my prostate, colon, or urinary system. My insurance policy does not cover colonoscopy or prostate evaluation, and I have been advised to consider these procedures, though they would cost nearly $7,000 out of pocket. While I understand the necessity of these assessments if needed, I prefer to seek a second opinion before committing to such expenses. It's important to note that there is a family history of cancer, primarily lung cancer. I welcome any advice or insight into my case and will provide any additional details you may require.
Gene Testing Outcomes Suggest Elevated Risk for MPN
A 27-year-old male of Irish heritage recently conducted a commercial gene analysis, and here are the findings: - **Rs12340895 (C;G)** Result Interpretation: "Doubles the likelihood of developing V617F-positive MPN." - **Rs3780374 (A;G)** Result Interpretation: "Significantly raises the probability of V617F-positive MPN manifestation." Based on my research, it appears that having these two genetic markers indicates a strong predisposition to this particular form of cancer. What steps should I consider taking to either prepare for or potentially postpone the onset of this condition? Should I discuss these findings with my healthcare provider? My studies suggest there isn’t a definitive cure for this condition.
Understanding Preseptal Cellulitis in Children
Hello everyone. I'm reaching out for assistance. My 6-year-old son recently experienced a concerning issue. He woke up on Friday with significant swelling around his eye, nearly closing it entirely. We quickly took him to the emergency room, where doctors diagnosed him with preseptal cellulitis. They prescribed antibiotics, specifically cephalosporin, as part of his treatment. However, after approximately 30 hours on the medication, I’ve noticed that his condition seems to have deteriorated. We’ve been applying warm compresses, which help reduce some swelling temporarily, but he now has a noticeable bump right in the center of the affected area. This morning, he woke up again with his eye completely shut. I’m uncertain whether I should return to the ER for further evaluation. I appreciate any advice or insights you can provide. Thank you!
14-Year-Old Male with Cough and Rash Symptoms
My 14-year-old son, who stands at 5 feet 3 inches tall and weighs 149 pounds, has been experiencing persistent cough and cold-like symptoms for slightly over a week. He stayed home from school on January 30 and February 3 as he was feeling unwell, but aside from that, he has managed to attend school. The predominant issue has been his cough. Initially, he had a runny nose for a couple of days, but that symptom has since resolved. He has not complained about a sore throat or experienced any fever. This afternoon, he reported developing a rash with red spots. He mentioned that it itches a little, but it's not uncomfortable, and he does not feel any pain. The rash is primarily located on his abdomen and chest, with some patches on his legs and a little on his arms, but there are no spots on his back. I checked his temperature, which was recorded at 99.4°F. He is fully vaccinated according to the standard vaccination schedule recommended by pediatricians in the United States. Our residence is near Vancouver, WA, in case that information is pertinent. Additionally, we have not changed any laundry or personal care products recently. What could this condition possibly indicate?
