I feel like my baby isn't totally secure. Am I doing something wrong?

If the wrap doesn't feel quite right, try checking these 3 things: 1) tighten! tighten! tighten! making sure to use the guiding edge to pull the correct piece 2) make sure the fabric panels across your back are in a flat position 3) make sure the 'x' on your back is in the center of your back, or higher if carrying a bigger baby.
