Not showing yet, is this normal?

I'm a total newbie, have spent the past week with flu and am a little worried. Am a few days shy of completing 12 weeks but am yet to show. There is a little bloat (I had more at 6weeks!) after eating and I still have symptoms like tender/sore breasts, little gas bubbles in the lower belly area and haven't had any bleeding at all but the nausea has subsided, my breasts that had swollen are back to normal size and I am worried something may have happened. Is the baby still growing/OK? My family doctor said as long as each time my fever (due to flu) spiked I took paracetamol to lower it everything ought to be fine, can't get an appt with my gyneo until next Weds. 
When did you guys start to show?
