Will this scar with a ridge flatten? (Photo)

Hello,That is just a mound of normal skin, and it is caused by the sutures under it pulling the skin together so much that it bulges up.  At twelve days your skin has not had time to make a scar. This mound will flatten with time, but you should be using tape therapy to mechanically support the skin and help minimize subsequent scar formation. Go to Amazon.com and get Hypafix tape and start using it soon. Best of luck!

Hello,
You'll be really surprised how much that incision will settle over the next few months. Unfortunately it typically just takes time. Be sure to keep follow-up with your surgeon so he/she can follow along and make sure you're doing everything to get the best scar but usually these flatten out with time. 
All the best in your recovery,

Thank you for sharing your question and photograph.  Ridging is not uncommon following an incision closure and tends to flatten very smooth over time.  This will improve as the swelling resolves and the tissues relax.  Hang in there!

Dear curiousmom88,I understand that you are worried about
your scar. However, you are still in the early
phase of the recovery period. Please do allow some time for the healing process
to occur. If after a few months, you are not satisfied with the appearance of
your scar, you can visit your plastic surgeon and discuss your concerns.Daniel Barrett, MD, MHA, MS
