I'm almost 7 weeks post op BBL and this one my stomach looks like, is this normal? (photo)

A lot of information is missing.  Preop photos would be helpful.  What did your abdomen look like before surgery.  You are likely swollen still. You may eventually need a tummy tuck when the swelling subsides.  

Some patients are better candidate than others.
Some surgeons are better than others.
The best results are always going to come from someone who is an ideal candidate and has their procedure done by someone with true expertise.
It appears you have muscle separation from previous pregnancies and some skin laxity. If paragraph both of these make you slightly less than ideal candidate.
Perhaps the fence removal could've been done a little more evenly.
It's a little hard to tell.
Your body post is a little off and how you took your picture.
Without an examination, before pictures or knowing how your procedure was performed no one can give you an accurate answer if this is normal.
Results are never perfect or a failure but rather somewhere on the spectrum.
Your results are normal for you based on what you look like before your procedure and how your procedure was performed.
Too many variables for any of us to give you a straight answer.
Best,
