Level 2 ultrasound

Everything seemed good. Next I seen the doctor, who I see at every single appointment. She said we wanted to make me an appointment to have a level 2 ultrasound, where they have higher quality equipment. She said that a small spot lit up on the brain area and they wanted to get a better view of the heart and bowel. She asked if I would want to go to the appointment (she didn't really tell me I was necessary). She said they will call me in a week with that appointment. She said everything else looked good. She said it was just cautionary and she honestly didn't seem worried at all. Also, baby girl was jumping the entire time and would not keep still. The poor ultrasound tech was so patient. 

Now, of course I'm going to worry. And I understand it's her job to be cautious. Just curious if anyone else had something similar happen and everything come out ok? She did say this was common and again, didn't seemed concerned.
