Pain During Pregnancy: Normal Aches vs Warning Signs

Pain during pregnancy is very common. Most of it comes from normal changes: the uterus stretching its ligaments, hormones loosening the pelvic joints, extra weight straining the back, and the baby pressing on nerves and organs. These aches come and go and ease with rest and position changes. Pain that is severe, constant, one-sided, or comes with bleeding, fever, fluid leaking, headache with vision changes, or reduced baby movements needs same-day care.

Also called: Pregnancy pain, aches in pregnancy, prenatal pain, abdominal pain in pregnancy

When to get help

Call 911 or go to the ER

  • Severe belly or shoulder-tip pain with fainting or dizziness in early pregnancy (possible ruptured ectopic pregnancy)
  • Heavy bleeding, soaking a pad an hour, or passing clots
  • Constant, severe belly pain with a hard, tender uterus, with or without bleeding (possible placental abruption)
  • Severe headache, vision changes or pain under the right ribs after 20 weeks (possible preeclampsia)
  • Chest pain, trouble breathing, or a seizure

See a doctor within a day or two

  • Regular, tightening contractions before 37 weeks, or a gush or trickle of fluid
  • Your baby moving less than usual after about 24 weeks
  • Pain with fever above 38 °C (100.4 °F), or burning urination with back or side pain
  • One-sided lower belly pain with spotting in early pregnancy
  • One swollen, painful calf

Book a routine appointment

  • Back or pelvic pain that limits walking, sleeping or daily tasks
  • Pain in the wrists and tingling fingers
  • Heartburn that does not respond to antacids

Usually safe to manage at home

  • Brief, sharp pains in the groin or lower sides when you stand up, cough or roll over
  • Mild aching of the lower back late in the day
  • Irregular, painless tightenings that ease with rest and water

Normal pain in early pregnancy (first trimester)

This page sorts pregnancy aches into normal and warning-sign pains by stage. For more on specific pregnancy aches, see pregnancy pain.

  • Mild cramping: period-like cramps as the uterus grows and implantation occurs. Mild cramps without bleeding are common.
  • Breast tenderness: soreness and swelling from hormones, often one of the first signs.
  • Bloating and constipation: progesterone slows the bowel.
  • Headaches: from hormone changes, caffeine withdrawal, tiredness and dehydration.

Normal pain in the second and third trimesters

Round ligament pain

The round ligaments support the uterus and stretch as it grows. They cause sharp, brief jabs or a pulling ache in the lower belly or groin, usually on one side or both, when you stand up quickly, cough, sneeze or turn in bed. It is most common between about 14 and 26 weeks.

Back pain

About two-thirds of pregnant people get back pain. The growing belly shifts your center of gravity, abdominal muscles stretch, and the hormone relaxin loosens ligaments. Sciatica, pain shooting down the back of the leg, can occur too.

Pelvic girdle pain

Pain at the front of the pubic bone (symphysis pubis dysfunction) or at the back of the pelvis, worse when walking, climbing stairs, standing on one leg or turning in bed. It can be quite disabling but responds well to physical therapy and a support belt.

Braxton Hicks contractions

Irregular, usually painless tightening of the belly from mid-pregnancy onward. They ease with rest, a change of position or drinking water. True labor contractions become regular, stronger and closer together.

Other common aches

  • Rib pain as the baby grows upward and kicks.
  • Leg cramps in the calves, mostly at night.
  • Carpal tunnel syndrome: tingling and pain in the hands from fluid retention.
  • Heartburn: burning behind the breastbone, worse after meals and lying down.
  • Lightning crotch: sudden sharp vaginal or pelvic pain as the baby's head presses down in late pregnancy.
  • Hemorrhoids: painful, swollen veins at the anus from pressure and constipation.

How doctors assess pain in pregnancy

Your obstetric provider will ask where the pain is, when it started, whether it comes and goes, and about bleeding, fluid leaks, fever, urinary symptoms and baby movements. They will check your blood pressure, examine your belly, listen to the baby's heartbeat and may do a pelvic exam. Tests can include urine tests for protein and infection, blood tests, an ultrasound to check the pregnancy and placenta, and fetal heart monitoring.

Safe pain relief during pregnancy

  • Rest and position changes: lie on your side with a pillow between your knees and under your belly.
  • Move slowly: roll to your side before getting out of bed, and keep knees together when turning.
  • Warm compresses or a warm (not hot) bath for back pain. Avoid hot tubs and saunas.
  • Pregnancy support belt for back and pelvic girdle pain.
  • Exercise: walking, swimming and prenatal yoga strengthen the back and core.
  • Physical therapy with someone experienced in pregnancy.
  • Supportive shoes with a low heel.
  • Prevent cramps by stretching calves before bed and staying hydrated.
  • Heartburn: small meals, avoid lying down after eating, and antacids approved by your provider.

Medicines

  • Acetaminophen (paracetamol) is the preferred pain reliever in pregnancy. Use the lowest effective dose for the shortest time and follow the label.
  • NSAIDs (ibuprofen, naproxen, aspirin at pain-relief doses) should generally be avoided from 20 weeks onward because of risks to the baby's kidneys and heart. Low-dose aspirin prescribed to prevent preeclampsia is different and should be continued as directed.
  • Check with your provider or pharmacist before taking any medicine or herbal product.

Frequently asked questions

Is it normal to have pain during pregnancy?

Yes. Mild cramps, round ligament pain, back pain, pelvic aches and Braxton Hicks contractions are very common and usually harmless. Pain that is severe, constant or comes with bleeding, fever, fluid leaking or reduced baby movements is not normal and needs prompt medical care.

When should I worry about stomach pain in pregnancy?

Worry if pain is severe, constant or one-sided, or comes with bleeding, fever, dizziness, fainting, shoulder-tip pain, regular contractions before 37 weeks, a severe headache or vision changes. Call your provider or go to labor and delivery or the ER.

What does round ligament pain feel like?

It feels like a sharp, brief jab or a pulling ache in the lower belly or groin, on one or both sides, often triggered by standing up quickly, coughing, sneezing or turning in bed. It lasts seconds to minutes and eases with rest.

Can I take ibuprofen for pain while pregnant?

Generally no, especially after 20 weeks, because NSAIDs like ibuprofen can affect the baby's kidneys and heart. Acetaminophen (paracetamol) is the preferred choice. Always check with your provider before taking any medicine in pregnancy.
