How far am I really?

I took a clear blue pregnancy test that said I was pregnant 1-2 weeks. But my last period started on September 14. Am I 1-2 weeks or am I 5 weeks like Glow thinks I am? I go to my doctor next week for blood work but I was just curious.
Woke up at 6am and couldn't go back to sleep. Baby dreams about my belly getting bigger. 
Also I've been cramping every time I go from sitting to standing or when I turn over in bed. Is this normal? 
Thanks 😊
