No Change After Gyno Surgery. How Long Should I Wait?

Hi there, I had Gyno surgery last week (3rd of June) to have the glands removed. Before surgery as well as having a large chest I also had very pointed nipples, I am now a week post surgery and although the pointed nipples are gone the actual breast like shapes on my chest still look as they did before the surgery? I am aware there would be swelling but my chest doesnt look swollen, just as it was before! Is it likely to be swelling and if so when would I be likely to see any changes? Thanks
