New experience!

This is my first pregnancy, and my EDD (estimated due date) is 12/10. I went to the doctor for cramping being so intense she she said my levels looked good via blood test but sent me for a ultrasound to rule out an ectopic pregnancy. I'm a little anxious, because the ultrasound tech didn't say much and was kind of rude because she said my doctor shouldn't have sent me already because it's too early to see anything. She wouldn't turn the screen for me to look, it was awful and made my anxiety worse. My fiance said he couldn't see anything (although I don't know that he knows what to look for). Is this normal at 4 weeks and 5 days?
