Don't know what to think

I'm 16 weeks pregnant and I don't feel pregnant at all . My boobs have been sore since about a week before I got my BFP. They usually hurt when I sleep on my stomach , are sore throughout the day and sometimes even when I walk . For the past 2 days , they have not been sore at all . I haven't had a whole lot of pregnancy symtoms to begin with and I am not showing yet so the lack of soreness in my boobs has me very worried . I have expressed that I'm worried , so I'd appreciate not saying "Consider yourself lucky."
