Ectopic Pregnancy

A man and a pregnant woman sit on a wooden bench outdoors, smiling with his hand gently resting on her baby bump, surrounded by greenery.

An ectopic pregnancy is when the fertilised egg implants outside the womb, usually in one of the fallopian tubes (95%).  As the fertilised egg begins to grow in the fallopian tube it can burst or severely damage the tube, resulting in internal bleeding which must be treated immediately. 

Ectopic pregnancies are considered a medical emergency as they can be life threatening. Unfortunately, an ectopic pregnancy cannot be moved into the womb and therefore can’t be saved.

Late or missed period

Symptoms of ectopic pregnancy can begin as early as 4 weeks and up to, or even later than, 12 weeks pregnant.  If you experience some or all of these symptoms it is important you see your doctor or specialist for a check-up straight away.
