They may try to predict O but it doesn't mean that's when you'll O. Plus, please understand that even if they have O correct, your LP will then be tacked onto the end of that time - you won't get your period the exact same day of the month you do this month. Your LP is added to the end of whenever you ovulate and stays the same length even when you ovulate late.
