What should you know about mild bicornuate uterus?

A bicornuate uterus develops before birth when the womb does not form as one typical cavity. The upper part may have two rounded spaces, while the lower womb and cervix can remain joined. The word mild describes the shape seen on imaging, not how you will feel or whether pregnancy will be affected. Many people discover the variation during an investigation for another reason.

Ask which scan established the shape and whether the cervix and lower womb were clearly seen. A [Pelvic MRI](/treatments/diagnostics-and-imaging/pelvic-mri/) may provide more detailed anatomy when ultrasound is unclear or another womb shape needs distinguishing. Share any history of pregnancy loss, preterm birth, unusual bleeding, or fertility concerns, because these details help tailor follow-up.

A bicornuate uterus is not usually an emergency. During pregnancy, contact your maternity team for bleeding, fluid leakage, regular painful contractions, or reduced fetal movement when you have been advised to monitor it. Outside pregnancy, seek urgent care for severe pelvic pain, fainting, or heavy bleeding.

How certain is the diagnosis? Is the cavity shape relevant to my pregnancy plans? Do I need specialist review or additional imaging, and what monitoring would be useful?
