Steroids before surgery

Hi everyone - a bit of a last minute query... I have my operation tomorrow to remove 3 wisdom teeth and was given a prescription for a bunch of the usual stuff. It said to start taking steroids the morning before... but I completely blanked and I'm taking them now (the night before)... My surgery is in the late afternoon and I was just wondering is this likely to cause issues? I'll take more tomorrow morning and then on day three before stopping but a bit paranoid now...
