Went for ultrasound. Thought I was 7 weeks and they told me I was about 5.5 weeks

I went for my first ultrasound today and my husband snd I were so excited to finally be able hear the heartbeat and see our baby on the screen. The woman doing my ultra sound said that she only saw a yolk sak, I was probably about 5 1/2 weeks (not 7 as we had thought), and had me schedule another ultra sound in 2 weeks.

It makes me a little nervous. Has any one else had this happen?
