Ultrasound was today and now I'm nervous

I had my ultrasound today and while she was looking at the baby's heart she asked me if I had an appt with the Dr today, I told her its next week. She double checked before I left and confirmed its next week. But now I'm nervous. Idk why she asked that or why she looked at the heart for so long.. I asked her if everything was ok she said yeah but I know they're not usually allowed to tell you anything anyways.. Ugh it's gonna be a long week now. Also the baby is measuring big, estimated 2 lbs 9 oz and 70th percentile.
