Well...dragon poo never smells particularly pleasant, but it really shouldn't be stinking up the whole house. If you can smell it across the room, there may be a problem. Coccidia is especially known for creating foul smelling poop. Reptiles in general mask signs of illness until sometimes it's too late. So while your dragon may appear to be acting normal, it could actually be sick. Best to get a fecal done since you haven't had one yet. I don't know where you're located, but in my area they cost me about 25 dollars and it takes only minutes to do. I always feel it's better to be safe than sorry! I wish you the best of luck.

Stare at me with empty eyes and
Point your words at me
Mirror on the wall will show you
What you're scared to see
I can see, yeah, wish I couldn't see at all
I can feel- Wish I couldn't feel at all
Hate to see- Wish I couldn't see at all
Hate to feel- Wish I couldn't feel at all
So climb walls,
Thin my blood now
And I crawl, back to bed now
