Signs Of Hiv My Ultrasound Shows "no Progress And No Signs Of Vitality"?

My ultrasound shows "no progress and no signs of vitality"? - signs of hiv

I want to about seven weeks, I had my second ultrasound yesterday. The doctor said that something is wrong - that pregnancy seems to have "ever" and that the fetus shows no sign of vitality, although it should be. He had no pulse. She said that the pregnancy stopped growing and that the fetus is 3 weeks shorter than planned.
She said that in a week to see if things have changed for the better.
I am very worried, and I wonder what the chances are that everything will go well? Has it happened to someone? I am preparing for the worst, I suppose.
