Should I be worried? Please help.

Claire
I'm 10w2d and my symptoms seem to have gone. No nausea, no tiredness, no sore boobs, and no bloating. 
​When I lie down flat I can breathe in and there's no belly at all :-(
​I'm hoping I'm just lucky but should I be worried?? 
​The only things that's stuck around is watery CM and bigger boobs (although they've not grown for last couple of weeks).  
​I'm freaking out but don't want to tell hubby and get him worried in case it's nothing. Please help :-( 
​I have my 12 week scan on 26th of this month but should I go in before??
