How to avoid ectopic pregnancy
Reduce your risk of sexually transmitted infections.
Sexually transmitted infections (stis) such as gonorrhea or chlamydia may increase a woman's chances of having an ectopic pregnancy. If you reduce your risk of contracting one of these diseases, you may reduce your risk of having an ectopic pregnancy as well.
Limit your number of sexual partners in order to reduce your risk of exposure. Always use a condom during sex to reduce your risk of contracting a disease.
