One week old - no engorgement?

My baby is now one week old, and I only experienced engorgement for like....a day and only in my left breast. I still get the feeling that there's little rocks in my breasts when it's been a little since he's eaten. My right breast never feels full. I feed on demand, and also pump and use a Haakaa sometimes. Is it normal not to feel full? I woke up this morning after going 4 hours without feeding him (he only ate on one side), and I barely felt full.
