Sky,
How long have you been tracking your cycles? are you 100% sure on your ovulations dates or tracking them by symptoms only? I only ask because there is no need to stress and worry if you aren't sure first. If you don't chart already, I would highly recommend it if you are concerned you might have a shorter luteal phase. That being said, there are supplements that could increase it a day or two. mine used to be 12-13 now its 14.
