What Causes Change In Stool Color And Palpitations After Taking Canesten?

hello. I took canesten (fluconazole 150mg) yesterday evening for thrush and today I noticed that my stool changed to a much brighter colour. I have been feeling a little bloated since a couple of days but otherwise I feel fine. Also I noticed some palpitations, but these may be due to the exam stress im in currently!? Should I see a doctor about the stool colour or wait and see how it changes?
