Short answer: Yes—pregnancy can cause stomach or abdominal pain, and many causes are harmless (gas, constipation, round‑ligament stretching, Braxton Hicks), but some causes need urgent care (ectopic pregnancy, miscarriage, preeclampsia, preterm labor, placental abruption, severe infection).
Common, harmless causes
- Gas and constipation from hormonal slowing of digestion can cause cramping, bloating, or sharp pains that improve with fluids, fiber, small meals, and gentle activity.
- Round ligament pain feels like brief, sharp pains on one or both lower sides, often with movement, and is common in the second trimester.
- Braxton Hicks (“practice” contractions) cause irregular tightening that eases with rest or hydration and is less intense than true labor.
When to seek urgent care?
- One-sided severe pain, shoulder-tip pain, or pain with bleeding in early pregnancy can signal ectopic pregnancy.
- Strong cramps with vaginal bleeding before 24 weeks may indicate miscarriage and need prompt assessment.
- Persistent upper right abdominal pain with severe headache or vision changes can be preeclampsia and requires hospital evaluation.
- Regular painful tightenings before 37 weeks suggest preterm labor and need immediate monitoring.
- Sudden constant pain with bleeding may be placental abruption and is an emergency.
Other conditions to consider
- Urinary tract infections can cause lower abdominal pain, burning urination, or fever and should be treated in pregnancy.
- Appendicitis or gallstones can occur during pregnancy and cause localized severe pain, nausea, and sometimes fever, seek medical care.
Practical relief tips
- Hydration, smaller frequent meals, fiber, and walking can ease gas/constipation; identify and avoid trigger foods and carbonated drinks.
- For round ligament pain, change positions slowly, use belly support, and rest as needed; consider gentle stretching if approved.
- Track patterns: worsening, persistent, or severe pain; pain with fever, vomiting, bleeding, fluid leak, dizziness, or reduced fetal movements warrants prompt medical advice.
