Introduction

Left lower abdominal pain during pregnancy may be caused by non-disease factors, but could also be related to medical conditions such as threatened miscarriage, gastroenteritis, or ectopic pregnancy, all of which might lead to pain in the left lower abdomen. If the pain worsens or vaginal bleeding increases, it is recommended to promptly visit a hospital gynecology department for diagnosis and treatment to prevent potential complications.

Pain in the lower left abdomen during pregnancy may be caused by non-disease factors such as the gradual enlargement of the fetus and uterus, or it could result from pathological conditions such as threatened miscarriage or gastroenteritis. It is recommended to keep warm, avoid cold exposure, get adequate rest, and, when necessary, follow medical advice for treatments such as fetal protection or anti-infective medications. The details are as follows:

I. Non-disease Factors

During pregnancy, as the fetus and uterus gradually enlarge, some women—particularly those with sensitive constitutions—may experience mild pain in the lower abdomen. If no other discomfort symptoms are present, special treatment is usually not required. However, attention should be paid to staying warm and getting sufficient rest.

II. Disease Factors

1. Threatened Miscarriage

In early pregnancy, especially before 28 weeks, if there are symptoms such as intermittent lower abdominal pain or vaginal bleeding, prompt visit to a gynecology department at a hospital is recommended to determine whether it is related to threatened miscarriage. If abdominal pain is mild and vaginal bleeding is light, medications such as dydrogesterone tablets or progesterone capsules may be prescribed for fetal preservation according to medical guidance.

2. Gastroenteritis

Poor dietary habits during pregnancy, including consumption of spoiled or contaminated food, can lead to acute inflammation of the gastrointestinal mucosa, which may also cause the aforementioned symptoms. Under medical supervision, supportive treatment with medications such as cefixime capsules, amoxicillin capsules, or omeprazole enteric-coated tablets may be recommended.

In addition, ectopic pregnancy may also cause pain in the lower left abdomen. If the pain worsens or vaginal bleeding increases, timely evaluation and treatment at a hospital’s gynecology department are essential to prevent potentially dangerous complications.

Can an ectopic pregnancy be detected with a pregnancy test strip?

Ectopic pregnancy—commonly referred to as “tubal pregnancy”—typically cannot be detected using a home pregnancy test (urine dipstick test), which only indicates whether pregnancy has occurred. If you experience any discomfort or concerning symptoms, prompt medical evaluation is strongly advised. Detailed analysis follows: Once ectopic pregnancy is confirmed, strict adherence to the physician’s treatment plan is essential. During conservative management, patients must remain on bed rest and avoid activities that may trigger rupture of the ectopic mass—such as vigorous exercise, bending over, or straining during bowel movements.
