Five Week Pregnant

CYN • Mother of 2 beautiful girls! 💕
According to my last cycle I'm 5 weeks and 2 days. I went  I the ER today and got a sonogram because I had pain on one side. They said everything was fine but they said that the sonogram is reading that I'm 4 weeks and one day. But that doesn't add up to me! What do you guys think?
