Risks for the woman
- Ectopic pregnancy
When an embryo implants in a Fallopian tube, the cervix or the abdoment, it is called an ectopic pregnancy. Ectopic pregnancies can be dangerous because the placenta can burrow into a blood vessel and cause major internal bleeding. We can usually detect an ectopic pregnancy by the level of hCG in pregnancy tests and an early ultrasound scan, but not always. Symptoms include severe, localised abdominal pain.
