Im no Dr, but I think its normal. U need to draw ur progesterone 7 days after ovulation to see if its low or not

The length of the first phase (pre-ovulatory) can vary within a woman's cycle - but the luteal phase usually remains the same. Ovulation can be delayed by a number of factors....stress, illness, medication, heavily increased activity, etc. Even if you do not ovulate around the normal time period - in knowing the length of your luteal phase you are aware of exactly when your menstrual period is due. This discounts the belief of those say they always have "late periods". If they were charting they would realize that actually it was just their ovulation being delayed and they were not late at all. A normal luteal phase is approximately 12 - 16 days and needs to be at least 10 days for implantation to take place. A short luteal phase can cause fertility problems making it difficult for a women to get pregnant.
