Ectopic pregnancy missed by ultrasound

User Profile
Yes, an ectopic pregnancy could definately be missed by an ultrasound. but within a few weeks of conception, you would normally have a great deal of pain and most likely, bleeding. if this is the case, make sure to go to the emergency room, as it is life-threatening. the main risk factor for ectopic pregnancy would be previous history of stds, as they scar the fallopian tubes and don't allow the fertilized egg to make it to the uterus. extrauterine and abdominal pregnancies can occur, but are rare.

Hi, and thanks for your medical question on eHealth forum!

You have not mentioned your symptoms, hence it is not possible to know whether you have ectopic pregnancy or not. Ultrasound done per abdomen in early weeks (first 5-6 weeks) can miss both ectopic and normal pregnancy. Before 5 weeks even a vaginal ultrasound can miss both the possibilities.

There are many factors that increase the risk for ectopic pregnancy. These are pelvic inflammatory disease, previous history of STDs, previous history of endometriosis, tuberculosis of genital tract, fibroids in uterus, smoking, fertility drugs like clomiphene and taking oral contraceptive pills irregularly. At times ectopic pregnancies occur without any cause.

If you suspect you have an ectopic, then go for a transvaginal ultrasound now (since your LMP is 5th of Jan, you are now 5 weeks pregnant) as a gestational sac (can be visualized by 4 and half to 5 weeks) and yolk sac (visualized by 5 or 5 and half week) will now be seen either in uterine cavity or in fallopian tubes as the case may be. Please consult a gynecologist ASAP. Hope this helps. Take care!
