A little upset right now

So today I had an ultrasound as I should be 9 weeks according to glow. I had a feeling I ovulated late and should be at least maybe 5-6 weeks at the earliest as I got my first positive January 22nd. But today when I had my ultrasound it took a while for her to finally find a sac that she measured at only 4 weeks. I don’t know what to think right now. It’s taking everything in me not to cry, there’s no way I’m only 4 weeks if I got my first positive on the 22nd. She isn’t an actual professional as she was trained on how to use the equipment but never actually worked in a doctors office (it’s a free clinic I went to until I can get in with my obgyn on the 20th. I’m afraid of what it could mean, and my cousin tried to reassure me that when she went there at about 5 or so weeks when she was pregnant they couldn’t really see anything either there, and that it’ll be okay. I just don’t know, and I’m sorry if this all seems jumbled or something. I was wondering if any of you had ever experienced something like this and had everything work out fine in the end? I haven’t really had any signs or symptoms for a loss as I haven’t had even the slightest bit of blood and no severe cramping though I have had some cramping that I was told was perfectly normal. I just need some reassurance to make me feel more calm
