Early ultrasound

So I had an early ultrasound today. I’m about 4w 6d if I go from Ovulation day but 6 weeks if I go from LMP

They did an early ultrasound because I had some light spotting and cramping. They wanted to rule out whether it was an ectopic pregnancy or not…the ultrasound tech kept asking if I was sure about my dates and that there wasn’t much of anything to show me on the ultrasound. A couple hours ago, a nurse called me saying my results were in and that I could either go into the walk in clinic to talk about them or book an appointment with the doctor in a couple days. Now I’m worried. 😭
