Differential Diagnosis for Abdominal Pain at 11 Weeks Pregnant

Single Most Likely Diagnosis

  • Round Ligament Pain: This is a common cause of abdominal pain in early pregnancy, especially around 11 weeks. The round ligaments stretch as the uterus expands, causing sharp pains or a dull ache in the lower abdomen.

Other Likely Diagnoses

  • Urinary Tract Infection (UTI): UTIs are common during pregnancy due to physiological changes that can predispose women to infection. Symptoms include abdominal pain, dysuria, and frequent urination.
  • Constipation: Constipation is a frequent complaint in pregnancy, caused by hormonal changes and pressure from the expanding uterus. It can lead to abdominal pain and discomfort.
  • Mild Preterm Labor: Although less common at 11 weeks, mild preterm labor can occur, characterized by regular uterine contractions leading to cervical change before 37 weeks of gestation.

Do Not Miss Diagnoses

  • Ectopic Pregnancy: Although the risk decreases after 6-7 weeks, an ectopic pregnancy can still present later, especially if there was an initial normal pregnancy confirmation. It's a life-threatening condition requiring immediate intervention.
  • Appendicitis: Appendicitis can occur at any gestational age and is a surgical emergency. The presentation might be atypical due to the pregnancy, making it crucial not to miss.
  • Placental Abruption: This condition involves the placenta separating from the uterus and can cause severe abdominal pain, vaginal bleeding, and fetal distress.
  • Ovarian Torsion: Although rare, ovarian torsion is an emergency that requires prompt surgical intervention to preserve ovarian function.

Rare Diagnoses

  • Pancreatitis: Inflammation of the pancreas can cause severe abdominal pain and is associated with high morbidity in pregnancy.
  • Gallbladder Disease: Gallstones and cholecystitis can cause right upper quadrant abdominal pain and may require surgical intervention during pregnancy.
  • Adnexal Torsion: Similar to ovarian torsion but involves the twisting of the entire adnexal structure, including the ovary, fallopian tube, and supporting structures.
  • Hepatic Hemangioma or Other Liver Pathologies: These can cause abdominal pain due to rupture or other complications, although they are exceedingly rare in the context of early pregnancy.
