Antibiotics before twilight surgery for breast argumentation?

I am at the end of a viral infection which has had me coughing. That part is better. Now I believe I am getting a slight sinus infection. I want to take a dose of amoxcilliin as I'm having breast argumentation in 4 days. I cannot postpone the surgery. I am having twilight surgery. Should amoxcilliin be fine? The surgeon will also administer an antibiotic before the surgery as well.
