Intensive follow-up is usually required for women with a final outcome of an ectopic pregnancy. This, however, only accounts for a small proportion of women with a pregnancy of unknown PUL location. There remains a clear clinical need to rationalize the follow-up of PUL so women at high risk of having a final outcome of an ectopic pregnancy are followed up more intensively and those PUL at low risk of having an ectopic pregnancy have their follow-up streamlined. This review covers the main management strategies published in the current literature and aims to give clinicians an overview of the most up-to-date evidence that they can take away into their everyday clinical practice when caring for women with a PUL %K ectopic pregnancy %K human chorionic gonadotropin %K pregnancy %K pregnancy of unknown location %K progesterone %K risk prediction models %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5557179/
