Groin pain in the first trimester: what to know

Early pregnancy can bring pulling or aching sensations in the lower abdomen and groin as tissues adapt. Muscle strain, constipation, urinary infection, or an unrelated hip problem can feel similar. The character of pain, whether it is one-sided, and associated symptoms are more useful than the location by itself.

Mild discomfort that settles with rest may be less concerning, but contact your maternity team for pain that persists or increases. Bleeding, shoulder-tip pain, dizziness, faintness, fever, painful urination, or marked one-sided pain needs prompt assessment because pregnancy-related causes must be considered.

Rest from lifting and high-impact exercise, change position slowly, drink fluids if you have no fluid restriction, and use a comfortably warm—not hot—pack briefly. Do not start medicines, supplements, or exercises for the pelvis without checking they are suitable in pregnancy. Keep a note of timing, severity, bleeding, and urinary symptoms for your clinician.

Seek urgent help for severe or worsening pain, vaginal bleeding, faintness, dizziness, shoulder-tip pain, fever, repeated vomiting, or pain with a very tender abdomen. Call your maternity service promptly if the pain is strongly one-sided or stops you from walking. Do not wait for a routine appointment when these warning signs appear.

Ask what examination or pregnancy assessment is needed, whether urinary testing is appropriate, and which comfort measures are safe for you. If symptoms are clearly movement-related after urgent causes are excluded, ask whether a pregnancy-aware physiotherapist can assess them.
