Ultrasound? Tubal?

I just had an ultrasound and the tech said she couldn't tell where the sac was located because it's too early. It still could be a tubal, depending on my HCG level and symptoms. Then she said it looks like a normal 5 week pregnancy and She said there was no internal fluid that didn't belong there. I'm still scared we could find out later that it is a tubal 😟 at this point, Im not even concerned about being sad about losing the pregnancy, I'm just scared that I'm going to end up in so much pain and possibly lose a tube 😔 I haven't had any bleeding but have had some light one-sided pain. My levels aren't rising like they should. 397, then 2.5 days later 486. Someone give me some advice! I'm really scared!
