Hi, Bridget, and welcome to Literotica and the Authors' Hangout in partiuular.
Unless is is intended for the current contest, you would be lucky to get it posted in 72 hours. Four days is more likely. If it is an illustrated story or a story with audio, it will take much longer, probably three weeks.
ETA: But don't go and click on the "pending." That will start the waiting period all over again.
