What should you know about TVS for ectopic pregnancy?

Transvaginal ultrasound, or TVS, uses a slim covered probe placed gently in the vagina to create images. It can show whether a pregnancy is visible inside the uterus and whether there is fluid or an unusual mass near a fallopian tube. Very early in pregnancy, the scan may not give a final answer. Clinicians may combine the findings with symptoms, pregnancy hormone tests, and a repeat scan. Ectopic pregnancy develops outside the uterus, most often in a tube, and needs timely medical assessment.

Tell the clinician the first day of your last period, any bleeding or pain, previous ectopic pregnancy, fertility treatment, pelvic surgery, or pelvic inflammatory disease. The scan is usually brief, and you can ask for an explanation before the probe is inserted. If an ectopic pregnancy is diagnosed, options may include close monitoring, medicine, or surgery; the choice depends on scan findings, symptoms, pregnancy hormone results, and overall health. A salpingectomy removes a fallopian tube when surgery is needed.

Seek emergency care for severe or one-sided pelvic pain, shoulder-tip pain, fainting, marked dizziness, heavy bleeding, or weakness during early pregnancy. These symptoms can signal internal bleeding. Do not wait for a scheduled scan if you feel suddenly worse. Pelvic pain can have several causes, so assessment is needed even when an ectopic pregnancy is not confirmed.

Ask what the scan found, whether the pregnancy location is definite, whether hormone testing or another scan is needed, and which warning symptoms should take you straight to emergency care.
