How long can an ectopic pregnancy be carried?

Never.: An ectopic pregnancy should never be carried. The nature of an ecotpic pregnancy is that it's located in a place that cannot support it for both the sake of the mother and the developing fetus. The fetus needs a placenta to implant in a place with good blood supply and a place that won't harm the mother and the only place for this is in an intact uterus. Otherwise there is a high risk of bleeding.
