Ultrasound anxiety

Waiting to do my first ultrasound to see baby! So so so nervous. OB did a abdominal one in the office but it wasn't showing a good picture. She could see the sac and what she thought was a heartbeat flickering but wanted a better one done same day today - even tho I had it scheduled for next Thursday. So now my husband is trying to rush here cuz he wants to be here. So nervous!
