RIGHT-SIDE PAIN DURING PREGNANCY: CAUSES WARNING SIGNS AND WHEN TO CALL YOUR DOCTOR

Feeling pain on your right side during pregnancy can be worrying, but in many cases, it is caused by the normal changes your body goes through as your baby grows. Mild discomfort is common, especially during the second and third trimesters. However, severe, persistent, or sudden pain should never be ignored because it may signal a condition that requires medical attention.

Understanding the possible causes can help you know when the pain is a normal part of pregnancy and when it is time to contact your healthcare provider.

Common Causes of Right-Side Pain During Pregnancy

Round Ligament Pain

One of the most common causes of right-sided abdominal pain is round ligament pain. As the uterus expands, the supporting ligaments stretch, causing a sharp or stabbing pain, usually on one side.

Round ligament pain often:

  • Appears during the second trimester.
  • Occurs when changing positions quickly.
  • Happens after coughing, sneezing, or standing up.
  • Improves with rest.

Although uncomfortable, this condition is generally harmless.

Growing Uterus

As your baby grows, the uterus places pressure on nearby muscles, ligaments, and organs. This pressure may cause aching or pulling sensations on either side of the abdomen.

Constipation and Gas

Pregnancy hormones slow digestion, making constipation and trapped gas very common.

Symptoms may include:

  • Cramping.
  • Bloating.
  • Sharp abdominal pain.
  • Pressure on one side.

Eating more fiber, drinking plenty of water, and staying active often help relieve these symptoms.

Braxton Hicks Contractions

Braxton Hicks contractions are "practice contractions" that prepare the uterus for labor.

These contractions are usually:

  • Irregular.
  • Mild.
  • Temporary.
  • Relieved by changing position or drinking water.

Unlike true labor contractions, they do not become stronger or closer together.

Less Common but Serious Causes

Although many causes are harmless, right-side pain can sometimes indicate a medical emergency.

Appendicitis

Appendicitis is uncommon but can occur during pregnancy.

Warning signs include:

  • Severe pain that worsens over time.
  • Pain moving toward the lower right abdomen.
  • Fever.
  • Nausea or vomiting.
  • Loss of appetite.

Appendicitis requires immediate medical evaluation.

Gallbladder Problems

Pregnancy increases the risk of gallstones due to hormonal changes.

Gallbladder pain may:

  • Occur after eating fatty meals.
  • Be felt under the right ribs.
  • Spread to the back or right shoulder.
  • Be accompanied by nausea or vomiting.

Kidney Stones or Kidney Infection

Pain caused by kidney problems is often severe and may occur in the side or back.

Additional symptoms include:

  • Painful urination.
  • Blood in the urine.
  • Fever.
  • Chills.
  • Frequent urination.

Prompt medical treatment is important.

Pregnancy Complications

In some situations, abdominal pain may be related to pregnancy complications such as:

  • Preeclampsia (especially with upper right abdominal pain, severe headache, vision changes, or swelling).
  • Placental abruption.
  • Preterm labor.
  • Rarely, ectopic pregnancy in early pregnancy.

These conditions require urgent medical assessment.

When Should You Seek Immediate Medical Care?

Contact your healthcare provider or go to the nearest emergency department immediately if right-side pain is accompanied by:

  • Heavy vaginal bleeding.
  • Leakage of fluid.
  • Fever.
  • Severe or worsening pain.
  • Pain that does not improve with rest.
  • Difficulty breathing.
  • Persistent vomiting.
  • Painful contractions before 37 weeks.
  • Decreased fetal movement after your healthcare provider has advised you to monitor fetal movements.
  • Severe headache or vision changes.

Do not wait for symptoms to improve if you experience any of these warning signs.

Safe Ways to Relieve Mild Pregnancy Pain

If your healthcare provider has confirmed that your pain is not caused by a serious condition, you may find relief by:

  • Resting on your left side.
  • Changing positions slowly.
  • Drinking plenty of water.
  • Eating fiber-rich foods.
  • Taking gentle walks.
  • Practicing prenatal stretching.
  • Wearing a maternity support belt if recommended.

Avoid taking pain medication unless it has been approved by your healthcare provider.

Can Right-Side Pain Be Prevented?

While not all causes can be prevented, you can reduce discomfort by:

  • Staying well hydrated.
  • Maintaining regular physical activity.
  • Eating a balanced diet.
  • Avoiding constipation.
  • Lifting objects carefully.
  • Attending all prenatal appointments.

Regular prenatal care helps identify potential complications early.

Final Thoughts

Right-side pain during pregnancy is often caused by normal changes such as stretching ligaments, digestive issues, or the growing uterus. However, severe, persistent, or sudden pain—especially when accompanied by fever, bleeding, contractions, or other concerning symptoms—should always be evaluated promptly.

If you are ever unsure whether your pain is normal, contact your healthcare provider. It is always safer to ask questions than to ignore symptoms during pregnancy.
