Delay in Menstruation After Taking Emergency Contraceptive

7/9/2025, 12:01:56 PMMale25-34

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

  1. Hormonal Effects of Emergency Contraception: The i-Pill can alter your menstrual cycle, leading to a delay in your period.
  2. Negative Pregnancy Tests: Consistent negative pregnancy tests are reassuring but not definitive by themselves, especially if your cycle is irregular.
  3. 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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

Seeking Relief for Persistent Ear Congestion

Hello everyone, I’m a 26-year-old male, standing 5'7" tall and weighing 134 pounds, currently living in the United States. For the past eight days, I’ve been struggling with a significant blockage in my ears. It emerged quite abruptly after I woke up, and I’ve been feeling a continuous pressure, much like the sensation of being airborne. Additionally, I’ve been dealing with nasal congestion for over a year, which might be attributed to chronic sinusitis or allergies. I’ve attempted the following remedies so far: * **Afrin** nasal spray, used twice daily for three days (I just completed this treatment) * **Sudafed** (pseudoephedrine) taken for a single day * A prescription medication that combines montelukast and levocetirizine, utilized over the last four days, as recommended by a doctor friend * I’ve also tried steam inhalation and the **Valsalva maneuver** for a couple of days to no avail Despite these efforts, both my nose and ears remain fully congested, with a particular emphasis on my left ear and nostril. I haven't noticed any fever or nasal discharge, but my hearing feels somewhat dulled on that side. Starting yesterday, I’ve occasionally felt a mild throbbing pain in my left ear, although it’s not intense. **Is there any other treatment I could explore before considering a visit to a healthcare professional or ENT specialist?** I’m reluctant to seek in-person medical help due to financial constraints, as I do not currently have insurance. However, if the situation worsens, I may have to reconsider… I appreciate any advice you might offer!

Elevated ALT and AST Levels in a 23-Year-Old Woman: Seeking Insight

After undergoing blood tests on July 1st, I received the results about a week later, revealing an ALT reading of 60 and an AST of 39. Then, on July 9th—early this morning—I had my bloodwork analyzed again, and this time my ALT surged to 118, while the AST also increased to 66, indicating both assays are elevated. The emergency room doctor I consulted expressed no worries about these findings, attributing them to my antidepressant medication. I am on Venlafaxine at a dosage of 75mg, which potential evidence suggests can elevate ALT levels in about 1% of users. Additionally, I take Vraylar at 3mg and Vyvanse at 70mg. I’m curious if it is indeed likely that my medications are the cause or if there might be another underlying reason for these spikes. I have a follow-up appointment with my psychiatrist, who ordered the initial tests, scheduled for the 11th of this month, and I'm also meeting a new primary care physician on the 23rd. I would appreciate any insights regarding whether the rapid increase and significant highs in my liver enzyme levels are alarming. For reference, my bilirubin levels were recorded at 0.2 both times I was tested. Thanks in advance for your help!

Immediate Assistance for Rash Concerns

A 21-year-old male, standing at 5 feet 6 inches and weighing 145 pounds, occasionally smokes and regularly takes Clonazepam (as needed) and Vyvanse (daily). While using Vyvanse to focus on schoolwork, I faced a period of intense stress, compounded by a significant episode of alcohol consumption. Initially, I attributed the emergence of certain rashes on my skin to random factors or possibly excessive drinking, or even a fungal infection. Fortunately, the rashes have since resolved. However, I've become aware that syphilis can present with similar skin irritations, which has left me feeling quite anxious about my health and uncertain if I should seek an STD test. The rashes first manifested during the last week of April, but due to my college commitments, I didn't pay them much attention at the time. They presented as random red circular spots that eventually peeled in the center, resembling scabs, and appeared all over both of my arms. The spots varied in size, darkened over time, and then faded away completely. Notably, I did not experience any rashes on my palms or soles, nor did they appear elsewhere on my body. I can't remember having a chancre at any point, although I did have a cold sore on my lip in March. While I will refrain from linking any images, I hope this summary provides sufficient context for further assessment of my symptoms.

Seeking Clarity on My Neck Ultrasound Results

Hello everyone, I’m an 18-year-old female and I have noticed several lumps in my neck that move slightly when I apply pressure. I’ve had about four of these lumps since 2022, though I can't be sure of the exact number. Fortunately, I haven't experienced any other symptoms. Occasionally, I do feel sharp pain in those areas, but it's not consistent. After undergoing an ultrasound, my doctor reassured me that everything appears normal, yet I can’t shake off my anxiety. Additionally, I had a chest X-ray and a complete blood count (CBC), both of which returned normal results. I appreciate any insights or information you can provide. Thank you for your support!

Neck Discomfort After a Sneeze

As a 21-year-old female, I find myself grappling with what seems like an insignificant question. Recently, I noticed that while sitting, I had my neck twisted at an awkward angle. When I sneezed, something unusual happened—I think I might have stretched my neck too far. My sneeze kind of paused abruptly because my neck snapped back, leading to a strange sensation that started in my neck and traveled up to my ear and forehead. Fortunately, this discomfort vanished within a few moments, and I now feel perfectly fine, aside from a slight sensation of strain in my neck area. Should I be concerned about this incident, or is it merely a product of my imagination?
