Do I have a uniboob? (Photo)

Hello there No I can't see symmastia there .Your shape will continue to evolve over 4-6 months so just relax and let your body heal .CheersTS

Although your concern is understandable, you do not have symmastia (uni boob). You may have some skin tenting when you lean forward. You may find the attached link, dedicated to symmastia surgery correction helpful to you for comparison purposes. Best wishes.
