possible cornual pregnancy?

Has anyone ever been diagnosed with a possible cornual pregnancy? Embryo implanted high in the corner of the uterus? What was your outcome? Did it end up being a successful pregnancy or was it a cornual pregnancy and later terminated? I'm 5w1d and my doctor said not to worry, he didn't think that's what this was, but the embryo has to grow in the right direction. The ultrasound was a difficult one, embryo is definitely high up.
