I noticed an odor from right breast incision, causing leakage and offensive smell. Is this normal? (photos)

Hi,over the last couple of days I have noticed an odour form my right breast,it's not foul more a weeping smell I do what've some yellowish fluid leaking as well,I still have my steri strips on so can not see the site,I'm due for these to be changed on Wednesday,they were changed two weeks ago. Should I be calling my dr to get it checked earlier? I have no symptoms of fever etc,I have just had an extremely bad cough for over a week which is mild now. I just slight moved my dressing and the smell is quite offensive I'm due for dressing change and appointment Wednesday. is it possible it's an infection?
