First ultrasound and sneak peek???

Hi ladies , I finally had my first ultrasound today, my last period was December 19th, but they are always all over the place. But I thought I was around 9weeks +.

My doctor gave me a due date of sept 24th, but today at my ultrasound the tech did trans vaginal and said it was all really hard to tell and see, but she said I’m actually only 6 weeks and 2 days pregnant.

I’m so sad, and I also did the sneak peek test, and I had a girl result so I assume that was probably inconclusive bc I was too early the entire time?
