Ultrasound showed nothing

Lyss
So this morning I went in for my first ultrasound I should be about 8 weeks. I didn't see anything on the screen but I kept waiting bc I'm not an ultrasound tech. But the ultrasound tech then said she was done. I asked why we didn't get to see the baby and if everything was ok. She said she wasn't allowed to say anything. I also got blood work done today. I called my emergency line at my obgyn and spoke I a dr. They said either I had a miscarriage or I'm having one or its to early. Has this happened to anyone? My husband and I are so upset and scared. We won't know anymore answers till Monday
