Concerns About Microcephaly: Awaiting MRI Results
At 25 years old, standing 5’4” and weighing 180 pounds, I'm currently 26 weeks into my pregnancy. I've attached ultrasound images and reports showcasing the facial profiles of my boyfriend and myself. Could it be that my baby just has a smaller head? My boyfriend has a somewhat slanted head shape, and previous ultrasounds labeled our baby's profile as normal, which now makes me question if that was accurate. Since the 20-week ultrasound, she has maintained her position—curled against my pelvis and facing my back—which makes her movements feel even more significant. I’ve heard many anecdotes of parents whose babies initially showed small head measurements but ended up being perfectly healthy. I realize that it’s not sufficient to conclude anything without further investigation; an MRI is needed to assess her brain's development. Just two days ago, I attended my maternal-fetal medicine (MFM) appointment, and honestly, everything felt overwhelming. When I review my past ultrasound reports, I see that her head was measuring at the 3rd percentile during the 20-week checkup, yet no one mentioned this to me at the time. The medical team stated that her positioning hindered them from completing the anatomy scan, scheduling a follow-up in four weeks. However, upon my return, her head circumference had plummeted to below the 1st percentile, alongside her biparietal diameter also dropping under 1%. Her weight decreased from the 32nd percentile down to the 12th. My primary OB assured me nothing appeared alarming, referring me to MFM solely to conclude the anatomy scan. Initially, I felt reassured until the doctor delivered the news of microcephaly, stating her head size and multiple other measurements had fallen below 1st percentile. Her weight is now at the 16th percentile, and they also noted a sloping forehead, with measurements falling -3 to -4 standard deviations from the norm. I had a meeting with a genetic counselor, and both my fiancé and I underwent blood tests. An amniocentesis was conducted the same day, and I’m now waiting for a call to schedule the MRI. Little explanation was provided beyond the fact that microcephaly can potentially result in developmental setbacks, seizures, and may hinder her ability to walk or speak. The uncertainty is terrifying, especially since I will be nearly 30 weeks pregnant by the time I receive results from the amnio, which takes about three weeks. They didn't clarify the purpose of the MRI, and my next growth ultrasound is scheduled for a month from now. I assume the MRI will assess whether her brain is developing normally, although current assessments suggest everything is typical except for the CSP being "sub-optimally visualized," whatever that implies. I find myself overwhelmed with anxiety to the point where it's affecting my appetite, leading to vomiting—something I know isn't healthy for my baby girl. Thankfully, tests for infectious diseases like Toxoplasmosis and CMV have returned negative. However, I’m facing another two weeks before receiving genetic results.

It's completely understandable to feel anxious during this waiting period regarding your baby's health and development. The concerns you've outlined, particularly about microcephaly and the head measurement results, are significant, and it's normal for such news to feel overwhelming.
Main Points
- Understanding Microcephaly: Microcephaly refers to a smaller than average head size, which can be related to various factors, including genetic conditions and brain development. The important thing is that not all instances lead to complications.
- Importance of the MRI: The MRI will provide detailed information about your baby's brain development, helping to identify any concerns that the ultrasound might not have captured.
- Managing Anxiety: Your anxiety and feelings of being overwhelmed are valid, and it's important to prioritize self-care during this challenging time.
Explanation
Microcephaly can indeed be concerning, as it may be associated with developmental delays or other health issues. However, as you've rightly noted, many factors can influence head size, and some babies with smaller head measurements develop normally. The results of your MRI and genetic tests will be key in understanding your baby's situation more clearly and determining whether any interventions are needed.
Next Steps
-
Focus on Self-Care: Try to find calming activities that work for you, such as:
- Deep-breathing exercises or mindfulness meditation to help manage anxiety.
- Gentle exercises, if cleared by your doctor, to help release tension.
- Ensure you're hydrating and trying to eat small, nutritious meals, even if your appetite is affected.
-
Keep a Journal: Document your feelings, thoughts, and any questions that arise as you wait for results. This can help in discussing concerns with your healthcare team.
-
Stay Informed, But Avoid Overwhelm: Research general information about microcephaly and brain development, focusing on reputable sources. However, limit how much you look into potential outcomes to prevent exacerbating anxiety.
-
Communicate with Your Healthcare Providers: If you have questions about the MRI or the process, don’t hesitate to reach out to your healthcare team. They can clarify the purpose and help ease your concerns.
-
Seek Support: It might be beneficial to talk to a mental health professional who specializes in maternal mental health to help navigate these feelings and provide coping strategies as you await more information.
Remember, you’re not alone in this process, and it’s perfectly okay to reach out for help when feelings of anxiety become overwhelming. You're doing your best, and taking care of yourself is essential for both you and your baby.

Help Needed: Facing Pinworm Issues Again After a Year
I’m reaching out for assistance as I’m struggling with a recurring pinworm infection. Last year, at the age of 28, I experienced this for the first time while working at a school. Although I sought treatment, the experience was mentally overwhelming, especially since I am diagnosed with OCD. It was so difficult that I ended up resigning from my position to avoid the risk of re-infection in that environment, effectively putting my career on hold due to this issue. I took albendazole numerous times and adhered strictly to hygiene practices, which initially seemed to work as the infection cleared up. However, to my dismay, exactly one year later, I began to notice that familiar itching sensation around my anal area. Panic set in immediately, and upon checking my stool, I was horrified to find pinworms. Throughout the entire year since my first encounter, I had diligently monitored my stool monthly and had never seen any evidence of reinfection or experienced any itching. Could it be possible that I contracted the infection from another source, or is it conceivable that I had it the whole year without realizing? I took rigorous precautions—ensuring that my family, boyfriend, and friends also took the necessary medication (both treatments) and even resorting to discarding my clothes and washing my sheets every day while constantly disinfecting surfaces. This situation has left me in a state of fear; I feel trapped in a traumatic cycle. I desperately need reassurance that this time, I don't have a lingering infection from the past year, and that I can successfully eliminate it once and for all. I’m on the brink of marrying my boyfriend and am also pursuing my master’s degree, but the stress has become almost unbearable to the point of suicidal thoughts. Will this nightmare finally come to an end?
Desperate for Help: Recurring Pinworm Infection After One Year
At the age of 28, I experienced a pinworm infection for the first time in my life. It occurred while I was teaching, and despite receiving treatment, the entire ordeal left a significant mental mark on me due to my existing OCD diagnosis. I was so overwhelmed that I made the drastic decision to leave my job, fearing I would get reinfected in the same environment—an action that cost me my career. I took albendazole numerous times, so far beyond counting that I’ve lost track, and adhered stringently to hygiene practices, successfully eliminating the problem. Now, exactly one year later—almost to the day—I felt the familiar, uncomfortable sensation around my anus. Anxiety took over as I rushed to the bathroom, and to my horror, I spotted pinworms in my stool. After the previous infection, I had taken to regularly checking my stool each month, and throughout the entire year, everything had seemed normal; no signs of pinworms and absolutely no itching. Could I have become infected again from a new source, or could it be that I had been harboring them for a year without realizing? Despite my efforts to ensure everyone in my life, including family, friends, and my boyfriend, took the medication (following both doses), I still found myself in this grim situation. I even opted to discard my clothes and bedding daily and diligently disinfected all surfaces. This experience has caused me intense fear, and my mind is spiraling. The trauma of it all has become too much to bear. I desperately seek reassurance that I haven't been suffering from this infection unknowingly for an entire year. I need to believe it is possible to eradicate it. With my upcoming marriage to my boyfriend and the stress of pursuing my master's degree, I feel overwhelmed to the point of despair. Will this ever come to an end?
Lorazepam Made Me Feel Really Nauseous
Age: 32, Male, Height: 5'4", Weight: ~150 lbs. I do not consume alcohol or drugs and generally consider myself to be in good health. After taking two lorazepam tablets on an empty stomach prior to a dental appointment, I quickly felt a sense of confusion and began vomiting within just an hour. Now, 12 hours later, I still feel ill; I’m less foggy than before but the vomiting has not subsided. I estimate I’ve been sick around 8 to 10 times since. I can't recall the exact dosage of the pills, but replacing them will lead to additional expenses. This incident has unfortunately ended my streak of 24 years without vomiting, which is quite disappointing. 😔
