No need to apologize. I know it's frustrating when you can't get a definite answer.
I would ask for another ultrasound, if you are pregnant (and I still think it's highly unlikely) then they will definitely be able to see the baby now.
One question, are you underweight? Have you lost allot of weight recently? Loosing weight quickly and or being underweight can cause your periods to stop.
There are so many possibilites, I don't want to give you a bunch of guesses. Isn't there a doctor where you are that will run tests and get to the bottom of this, because this isn't normal.
I really hope that it all works out for the best, but I still say get this checked, because you're right, something is going on and you need to find out what it is.
Good luck and keep us posted.
