13w3d and do not even feel pregnant at all???

Summer
I'm really worried. I'm not sure if this is normal or not. I've had 2 previous losses (1 blighted ovum and 1 missed miscarriage). My last ultrasound was at 10 weeks and all was great. I did the genetic testing and I found out I'm having a boy. I haven't had many symptoms this pregnancy other then headaches and I had slight pulling feelings around 12 weeks. Is it normal to not feel any pulling or growing pains?
