14 Weeks Pregnant.

I'm currently 14 Weeks 2 days and I just don't feel pregnant, Is this normal?. I've had 3 scans last was 2 weeks 3 days ago, & Every thing is fine and normal. Some days I can see a small bump, then the next my belly seems softer and flabby. I Keep getting random pains in my side's and lower abdomen (I don't know what pains are or aren't normal). I don't know I think I'm just over reacting as this is my first successful pregnancy. I'm to see midwife in 10 days hopefully she can reassure me a little.
