Greasy oily stool??

So weird and gross but....I have literal oil in my stool the past 2 days. Its drops of oil floating on top of the toilet water. I have not changed my diet. I havent been eating out. I'm not super adventurous with food. Nothing is new or has changed as far as diet or meds. I've never experienced this. Any ideas? I already messaged the doctor but not worth calling after hours will wait for her to call me in the AM.
