Understanding the Nub Theory in Pregnancy: Myth or Reality?
During a recent 12-week ultrasound, the nurse suggested that I might be having a boy based on the upward angle of the nub. This concept was entirely new to me and seemed quite unbelievable at first. However, I've since noticed that discussions around this theory are rampant on various forums and Reddit communities geared towards expectant mothers.

The Nub Theory, often discussed in pregnancy forums, suggests that the angle of the 'nub' (the genital tubercle) observed during an early ultrasound can predict a baby's sex. While many parents find this intriguing, it's essential to understand its accuracy and limitations.
Explanation
The Nub Theory is based on the idea that the angle of the nub can indicate whether you are having a boy or a girl. Typically, if the nub is angled upwards at greater than 30 degrees, it may be interpreted as a boy, while a flatter angle might suggest a girl. However, this is not a medically accepted method for determining sex. Ultrasound professionals usually rely on more definitive markers closer to the 20-week scan when external genitalia are more developed.
Next Steps
-
Stay Informed: While it's fun to engage in discussions about the Nub Theory, remember that it is not scientifically proven. You may want to read reputable sources or talk to your healthcare provider for accurate information regarding fetal development.
-
Look Forward to the 20-Week Ultrasound: The anatomy scan around 20 weeks is the standard time when sex determination is most reliable. This will provide you with a clearer picture.
-
Connect with Support Groups Carefully: Engaging with communities can be enjoyable, but ensure you critically evaluate the information shared and refrain from making any significant decisions based solely on theories like the Nub Theory.
It's completely natural to feel excited and curious about your baby's sex. Embrace these discussions, but prioritize evidence-based information when it comes to your pregnancy journey. Let me know if you have other questions about pregnancy!

Understanding the Long-Term Impact of ADHD Medication
A 55-year-old male, of Asian Indian descent and a US citizen, was diagnosed with adult ADHD one year ago. Initially prescribed a dosage of 70 mg of Adderall, he experienced severe insomnia, struggling to sleep for two consecutive nights after administration. His physician gradually reduced the dosage over several months until he reached 10 mg per day. However, he continues to experience significant side effects even at this lower level, including persistent sleeplessness and racing thoughts throughout the night. Is this a common reaction? To achieve therapeutic benefits, he feels that a minimum dosage of 20 mg is necessary, and he typically takes it twice daily at 8 AM and noon on weekdays.
Concern About Brief Marijuana Exposure During Pregnancy: What Are the Risks?
Hello there! I'm a 30-year-old woman with no significant medical issues, currently serving as a gestational carrier at 30 weeks of pregnancy. Today, I encountered a situation that has left me feeling quite anxious. I inadvertently walked into a cloud of marijuana smoke while on a covered patio. At that moment, someone nearby exhaled from a bong just as I arrived. I believe I was exposed for no longer than five seconds before I quickly moved away. The individual was essentially right next to me. Please note that I do not use marijuana myself. My main concern revolves around potential drug testing after delivery and the implications for my baby. With my first child, drug tests were performed at birth (including urine, cord tissue, and meconium), and all came back negative for any substances—this was in light of having had no exposures. I have several inquiries regarding this incident: 1. What are the chances that such minimal secondhand smoke exposure could result in enough THC entering my system to yield a positive urine test? 2. If I receive a negative result on urine testing within the next 24-48 hours, does this suggest that my exposure level wasn’t significant enough to create a positive meconium test for the baby? 3. Is there any research indicating that brief encounters with marijuana smoke can lead to positive meconium tests in newborns when the mother has not used the substance? Aside from this incident, I am in good health, avoid regular exposure to smoke, and this was an isolated occurrence. I'm just seeking clarity on the actual medical risks involved.
Could It Be Pregnancy?
I’m a 19-year-old male, weighing 63 kg and standing 172 cm tall. My girlfriend, also 19, is 70 kg and 169 cm. Neither of us is taking any medications. Last year, on October 31, my girlfriend and I were intimate. She has a menstrual cycle that typically lasts 36 days. During our encounter, we ensured to use condoms. She experienced her period on November 22 (36 days after our encounter) and again on December 31 (this time 39 days later). On December 16, she had a bout of vomiting and diarrhea in the evening, but she felt better afterward. Recently, she’s noticed some breakouts on her forehead. Her next period was expected on February 5, but it hasn’t appeared yet. Are we in the clear regarding pregnancy concerns?
Health Concerns Could Hinder My Enrollment in Dream Graduate Program
Hello, I’m a 25-year-old male, standing 5'10" and weighing 185 lbs. I identify as White and I only drink alcohol occasionally, roughly one to three times a month. Importantly, I do not smoke nor do I use recreational drugs. I've been grappling with a medical issue that has yet to receive a specific diagnosis. This condition is characterized by a pain that occurs in the back of my head accompanied by a sensation of warmth or feverishness at times. Previously, the discomfort was quite intense. Thankfully, my primary care physician prescribed a regimen that includes muscle relaxants (Cyclobenzaprine, 10MG) and anti-inflammatory medication (Meloxicam, 15MG). Since starting this treatment, the headaches have dissipated, and the fever-like symptoms have become infrequent, occurring maybe once a month. Unfortunately, exposure to colder weather tends to exacerbate the feeling of warmth and fever. With the recent drops in temperature and snowfall, I’ve started experiencing these symptoms more frequently again. Adding to my concerns, I've just been accepted into a graduate program at my dream university situated in the Northeast, but I'm now contemplating the possibility of choosing a different school. The cold climate there is making me anxious about frequent episodes of what feels like a fever. I am reaching out for thoughts on what could possibly be causing these issues, as well as suggestions for more effective long-term treatment options. My primary care physician can be somewhat difficult to contact, so I would like to arrive at my next appointment, whether it’s with her or a new doctor, with some insights into what I might be experiencing.
