If you can go 7 weeks without stretching your scars, you are well ahead of normal expectations and should be okay. Your skin can stretch after that, but shouldn't much.
My situation is abnormally intense, and I have never, ever been able to let my incisions heal "safely" or carefully. I did a lot of stretching, lifting, taking blunt force blows to the sites, etc. The scars I have seem to vary more in connection to the particular surgeon than to the situation after the surgery, though.
I've learned over the years to value surgical alterations that hurt less over those that look pretty. My least favorite site (and the one that is on my mind the most) is my right ankle, where a rockstar sports medicine guy tried to remove titanium pieces that didn't want to come out. He left me unstable and in chronic pain, and made it where I couldn't do my favorite things - hiking, basketball, roller skating - anymore.
My ugliest and nicest scars are both from the same surgeon. The ugly side is the result of an emergency surgery to deal with a hematoma, and the nice side is a simple removal of breast tissue by an oncologist who usually deals with breast cancer.
