4.6 week ultra sound?

Ashley • 30. Dog mom, cat mom. Pregnant with baby #1
My SIL is a pediatric nurse and works nights. It's a slow night for her and she just offered me a free ultra-sound. I'm only 4 weeks and 6 days, maybe 5 weeks.. would it be worth it? From Googling, I know there wouldn't be much to see and we definetly wouldn't be able to hear/see a heartbeat. 
Would you do it?
