Should I be worried??

I went in today for my first ultrasound and found out I wasn’t 8 weeks. My gestational sac was actually measuring at 6 weeks. My last period was December 23rd, 2018 and my cycle lengths are pretty long, about 44 days. This is what my ultrasound looked like. My doctor scheduled me for another ultrasound next week. Should I be worried?
