6 week ultrasound-2 gestational sacs?!

Knottiee1a8ac930dedf8d0

I am an OB nurse and I did an trans abdominal ultrasound on myself at 6 weeks, before my first appointment. I am seeing two gestational sacs. Does anyone else see this or have experience with early ultrasound in twin pregnancy?<img src="https://us.v-cdn.net/5020794/uploads/editor/cz/zolzqgj1cu4n.jpeg" alt="" />
