So nervous I could cry!

Jacie • 26 years old, pregnant with my second but first baby with my husband! Couldn't be more thrilled!
My first ultrasound is tomorrow and I am terrified they won't see anything or no heartbeat! I should be 7 weeks 3 days but I think I ovulated late so I should be more around 6 and 3 days. Did anyone else see the heartbeat at 6 weeks???
