Ultrasound done 2 days ago the day you period was to start because you were having abnormal abdominal pain and they did not mention that you were pregnant Could you still be pregnant?

When you go to the hospital to have an ultrasound done no matter the case, they are not able to tell you anything about the ultrasound. (The technician)

When you are seen afterward by the doctor or nurse or by the time of discharge they would absolutely tell you if you were pregnant, as well as how far along you are. So to answer your question if they didn't mention it, it is because you are not pregnant. You might not see a pregnancy until your hcg is at certain level. However, I would assume they would have done blood work and possibly a pregnancy test.
