What is a one-sentence summary of the following article?
If your round ligament pain is accompanied by vaginal discharge or bleeding, your doctor needs to know as soon as possible. Also contact your doctor immediately if you see any of the following: Pain that lasts more than a few seconds New symptoms like low back pain, fever, chills, faintness, and nausea and vomiting beyond the first trimester Constant pain or pressure, pain or discomfort when walking, pain when urinating, and increased pressure in your pelvic region can be warning signs of something more serious that just round ligament pain. Contact your doctor as soon as possible if you experience these symptoms. Labor pain does not typically occur until the third trimester. Round ligament pain begins during the second trimester, as the uterus begins to grow and expand. Round ligament pain can be confused with Braxton-Hicks contractions. While this form of contraction can begin during the second trimester, a Braxton-Hicks contraction is not painful.

Summary:
Contact your doctor with any sudden onset of pain. Talk to your doctor if your pain persists. Avoid confusing round ligament pain with actual labor.
