So my last period was November 10th. My period was due December 8, I took a test and it was positive on the 8th, I had taken one on the 6th and it was negative, which would put me at 6W2D today. I had an appointment today and they did a transvaginal ultrasound and said I'm not nearly as pregnant as I thought, she's guessing between 4 and 5 weeks. How is that possible? We were going to tell our families tomorrow and now I'm freaking out that there's something wrong. We told my kids 2 weeks ago.
