One Breast Nice and Round Other is Flat on Side and Oval Shaped?

When implants are first inserted, they sit high up because your tissues are tight and gravity hasn't taken effect. Over time, natural tissue expansion occurs to allow the implants to fall into place. By this time, your breasts will have taken on a more natural contour, where the lower breasts become softer and rounder. Please wait at least four months for this to happen.This process tends to occur sooner in one breast than the other, so don't be alarmed if you find that your left drops before the right or vice versa.

One week after surgery is too early to make any judgements on breast shape.  Swelling is still present and the implants will take some time to settle.  Also, your skin and muscle will stretch and relax over time.  Talk to your plastic surgeon and make sure your questions and concerns are addressed. 

One week after surgery is a little early to get worried.  Without seeing your before and after pictures, it is impossible to give you further advice.  I would suggest talking over your concerns with your surgeon.

 

Good luck.
