"As long as there room viable cultivation placenta cells, those tests can be positive," Dr. Williams says.
An ectopic pregnancy happens as soon as a fertilized egg ends up farming outside the uterus—usually in a fallopian tube—instead of within the uterus7. Yet it's worth understanding that one ectopic pregnant can also happen in various other reproductive locations like the ovary or cervix. An ectopic pregnancy isn’t viable since the embryo isn’t inside the uterus where it deserve to grow and thrive.
