Thought I was almost 8 weeks but I’m actually 6 weeks 5 days

Madison

So I had my first ultrasound a couple days ago and they said there was just a slight worry because we thought I was 8 weeks but I’m measuring at 6 weeks. I’m now 6 weeks 5 days, Has this happened to any of you? I need positive feedback please. I’m really nervous because it’s my first pregnancy and I just need all the positive stories/vibes that I can get. Please help!
