Stomach pain in the second trimester is often due to round ligament pain. Your womb is expanding and this can cause the ligaments to stretch.

This can cause pain in your lower tummy, groin or hips on one or both sides. It is important to get checked by your GP, obstetrician or midwife if you have pain like this.

There are some things you can do to help with pelvic ligament pain:

  • lie on the opposite side to the pain
  • take your time when moving, especially when turning in bed at night
  • take a warm bath

Sometimes pain in your pelvic area can be caused by pelvic girdle pain.

You should lie on your side when you're pregnant. It can help prevent stillbirth.

When to get medical help in your second trimester

You should contact your GP, maternity unit or hospital if:

  • you have pain passing urine (when you pee) - this could be a sign of a urine infection
  • you have blood in your urine or smelly or cloudy urine - these could be signs of a urine infection
  • you have any bleeding from your vagina - this could be a sign of a miscarriage or a problem with your placenta
  • the pain is higher up in your stomach or chest, or if you have a headache, swelling of your hands, feet and face or blurring of your vision - these are signs of pre-eclampsia
  • the pain is severe, or if it is mainly on one side - this could be a sign of appendicitis
  • you notice any change in your baby’s movements
  • you feel a gush of fluid - this could be a sign of premature labour
