Your health matters just as much as your baby's. If you are dealing with appendicitis signs during pregnancy, here is what you need to know.
The short answer
Appendicitis is the most common non-obstetric surgical emergency during pregnancy, occurring in about 1 in 1,500 pregnancies. Diagnosis can be challenging because the growing uterus shifts the appendix upward. Prompt surgical treatment is safe during pregnancy and prevents the serious complication of appendix rupture.
Key takeaways
- Appendicitis is the most common non-obstetric surgical emergency during pregnancy, occurring in about 1 in 1,500 pregnancies. Diagnosis can be challenging because the growing uterus shifts the appendix upward. Prompt surgical treatment is safe during pregnancy and prevents the serious complication of appendix rupture.
- Usually normal when: Mild abdominal discomfort related to normal pregnancy changes (round ligament pain, gas, constipation)
- Call your doctor if: Severe abdominal pain, especially on the right side, with fever, nausea, and vomiting
- Varies by age — see the age-by-age breakdown below
“About 1 in 8 women experience symptoms of postpartum depression. If you have symptoms of depression that last longer than 2 weeks, tell your health care provider.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to ACOG, NIH, Mayo Clinic guidelines, appendicitis is the most common non-obstetric surgical emergency during pregnancy, occurring in about 1 in 1,500 pregnancies. Diagnosis can be challenging because the growing uterus shifts the appendix upward. Prompt surgical treatment is safe during pregnancy and prevents the serious complication of appendix rupture. At First trimester, appendicitis symptoms in early pregnancy are similar to non-pregnant presentation: pain beginning around the navel and migrating to the lower right abdomen, loss of appetite, nausea, and sometimes fever. However, these symptoms can mimic ectopic pregnancy or ovarian cyst torsion, making careful evaluation important. It is generally considered normal when mild abdominal discomfort related to normal pregnancy changes (round ligament pain, gas, constipation). However, you should contact your pediatrician promptly if severe abdominal pain, especially on the right side, with fever, nausea, and vomiting.
Normal vs. Concerning
By Age
What to expect by age
First trimester
Appendicitis symptoms in early pregnancy are similar to non-pregnant presentation: pain beginning around the navel and migrating to the lower right abdomen, loss of appetite, nausea, and sometimes fever. However, these symptoms can mimic ectopic pregnancy or ovarian cyst torsion, making careful evaluation important.
Second trimester
As the uterus grows, the appendix is displaced upward and laterally. This means appendicitis pain may be felt higher than the typical lower-right location - sometimes in the mid-right abdomen or even the right flank. Ultrasound and MRI (without contrast) are safe diagnostic tools during pregnancy.
Third trimester
Diagnosis is most challenging in the third trimester as the appendix may be near the rib area. The risk of appendix perforation is higher during pregnancy, partly because diagnosis may be delayed. Laparoscopic appendectomy can be performed safely during pregnancy. Delay in treatment increases risks for both parent and baby.
What to Tell Your Pediatrician
- Describe when you first noticed appendicitis signs during pregnancy and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if persistent right-sided abdominal pain that is new and different from pregnancy-related discomfort.
- Mention if abdominal pain with loss of appetite or nausea unrelated to morning sickness.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Mild abdominal discomfort related to normal pregnancy changes (round ligament pain, gas, constipation)
- Persistent right-sided abdominal pain that is new and different from pregnancy-related discomfort
- Abdominal pain with loss of appetite or nausea unrelated to morning sickness
- Severe abdominal pain, especially on the right side, with fever, nausea, and vomiting
- Pain that started near the navel and moved to the right side
- Abdominal pain that worsens with movement, coughing, or pressing on the area
What You Can Do at Home
- Keep track of when you notice appendicitis signs during pregnancy — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that mild abdominal discomfort related to normal pregnancy changes (round ligament pain, gas, constipation) — this is generally within the range of normal.
- At First trimester, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Prioritize your own rest and nutrition. Accept help when offered, and do not hesitate to reach out to your healthcare provider.
- While monitoring at home, seek immediate care if severe abdominal pain, especially on the right side, with fever, nausea, and vomiting.

Gallstones During Pregnancy
Gallstones are more common during pregnancy due to elevated estrogen and progesterone, which increase cholesterol in bile and slow gallbladder emptying. They affect 5-12% of pregnant people. Many gallstones cause no symptoms, but gallbladder attacks can cause severe pain in the upper right abdomen and may require treatment.
Round Ligament Pain in Pregnancy
Round ligament pain is a sharp or jabbing sensation in the lower belly or groin area caused by the stretching of the ligaments that support the uterus. It is one of the most common discomforts of pregnancy, especially during the second trimester, and is not harmful to you or your baby.

Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
