Pregnancy is often described as a journey of wonder, but for many women, it is equally a journey of inexplicable and sometimes alarming bodily changes. A recent viral moment has highlighted just how confusing these changes can be, as a woman shared a bizarre pregnancy symptom that left millions of viewers both amused and deeply concerned.
Steph, a lawyer and TikTok creator who goes by @by.steph_, posted a video documenting a strange phenomenon occurring in her abdomen. In the clip, as she moved her fingers across her stomach, loud, audible “gassy” sounds echoed from within. The sounds were so unexpected that even Steph appeared surprised, her eyes widening as the noises repeated.
The video quickly resonated with a global audience, amassing 3.6 million views. However, the reaction from “netizens” was sharply divided. While some viewers found the sounds humorous, others were genuinely frightened for the mother-to-be, with several commenters urging her to “run to her doctor” immediately. Some speculated that the noise was caused by the baby or the amniotic fluid surrounding the fetus.

The Anatomy of the ‘Gassy’ Belly
While the internet speculated wildly, the medical explanation is far less mysterious. Dr. Franziska Haydanek, an OB-GYN, clarified that the sounds heard in the video are almost certainly not coming from the baby or the amniotic sac, but rather from the woman’s own digestive system.
As a pregnancy progresses, the growing uterus requires more space, which forces the surrounding internal organs to shift. By the time a woman reaches the second trimester—Steph was 21 weeks pregnant at the time of the video—the uterus has expanded significantly, pushing the intestines higher into the abdomen. This compression can trap gas and alter the way the digestive tract functions.
the stomach itself undergoes a physical shift, tilting upward by nearly 45 degrees to accommodate the fetus. This anatomical rearrangement brings the stomach and intestines into closer proximity and closer to the abdominal wall. When external pressure is applied—such as Steph moving her fingers across her belly—it can displace gas within the intestines, creating the loud, squelching or “gassy” sounds captured in the video.
From a clinical perspective, This represents a common occurrence. The compression of the digestive organs is also the primary reason why many pregnant women experience increased indigestion and heartburn, as the stomach’s tilt and the pressure from the uterus can allow gastric acid to move more easily into the esophagus.
Amniotic Fluid vs. Intestinal Gas
Many of the concerned viewers suggested that the sound was caused by amniotic fluid. To understand why this is unlikely, it helps to look at the role of this fluid. Amniotic fluid is a clear, odorless substance that cushions the fetus, protecting it from physical impact and allowing for the development of the lungs and digestive system.
According to the Cleveland Clinic, the fetus practices swallowing and breathing by drinking this fluid, which is then excreted back into the sac. While there is a significant volume of fluid—peaking at nearly one liter between 34 and 36 weeks—it is contained within the amniotic sac. Pressing on the abdomen does not typically produce “gassy” sounds from the fluid itself, as the fluid is not compressible in the same way that air in the intestines is.
Dr. Haydanek noted that the act of pressing on the belly, as seen in the TikTok video, does not cause harm to the baby. In most cases, these sounds are entirely harmless and are simply a byproduct of the body making room for a new life.
Distinguishing Harmless Sounds from Warning Signs
While the “belly sounds” in this instance were benign, the viral reaction underscores an important point: knowing when a symptom is a quirk of pregnancy and when it is a medical emergency. In the excitement of social media, critical health advice can sometimes be lost, but maternal health depends on recognizing genuine red flags.
Medical professionals emphasize that while gas and indigestion are normal, other symptoms require immediate intervention. The Centers for Disease Control and Prevention (CDC) lists several urgent warning signs that should prompt a call to a healthcare provider:
- Severe or persistent headaches that do not improve with rest.
- Sudden changes in vision, such as blurring or seeing spots.
- Extreme swelling in the face, hands, or legs.
- Fainting, severe dizziness, or shortness of breath.
- A high fever or chills.
- A noticeable decrease or total stop in the baby’s movement.
- Vaginal bleeding or the leakage of fluid.
- Severe abdominal pain or nausea that does not subside.
The general rule of thumb for expectant parents is simple: if something feels fundamentally “wrong,” it is always safer to consult a professional than to rely on the consensus of social media commenters.
Common Second-Trimester Physical Shifts
| Organ/System | Change | Common Symptom |
|---|---|---|
| Uterus | Rapid expansion upward | Increased abdominal pressure |
| Stomach | Tilts upward (~45 degrees) | Heartburn and acid reflux |
| Intestines | Displaced and compressed | Gas, bloating, and constipation |
| Diaphragm | Pushed slightly upward | Shortness of breath |

For Steph and millions of others, the experience of pregnancy is a lesson in the body’s resilience and its capacity for change. While the sounds of a “gassy belly” may be startling, they are often just a reminder of the complex internal choreography required to support a growing fetus.
The next standard checkpoint for most women in Steph’s position is the anatomy scan and subsequent monthly prenatal visits, where OB-GYNs can provide personalized reassurance and monitor the health of both mother, and child.
