I’m scared y’all 😢

So I pee’d On three test all came back bfp, then I am 6 days late for my period and supposed to be 5 weeks according to lmp. But today they did an ultrasound not the transvaginal tech said she didn’t see anything in my uterus. Is this normal? What’s wrong with me? Shouldn’t they see at least a sac?
