Cornual, Angular, High implantation?

LeggoMyPreggo

So, long story short, I have been in for ultrasounds since 5 weeks. The ultrasound tech said, "Oh, it's really high.". I thought nothing about it, and went home happy.

So we went in for another U/S a week later and she said, "Yea it's really high, close the tube. It would be considered cornual." I asked the doctor about it during our consultation and he basically said, no worries, we just need to watch it. I went home hesitantly satisfied.

A week later, we did another U/S yesterday, and the tech says "Remember how we are watching to see if it grows towards the tube? It looks like it's growing that way so that's worrysome." Again, I asked the nurse about it and she says basically no worries, we will just watch it. So, I've got an U/S tech telling me that I've got a cornual pregnancy, and a doctor that says "Don't worry about it, but you're high risk, so keep coming back every week. Any sharp pains and we need to know about it." Talk about frustrating. Anybody have the same high implantation problem? I can't find a lot of info, and I'm led to believe it is rare.
