...or are you saying you ovulate twice in a calendar month? Like an ovulation early in the month, then a period, followed by another ovulation at the end of the month (so two different cycles)? If so, then that can be normal (as long as it only happens a few times per year), since most women have cycles that are slightly shorter than a normal calendar month.
Why do you think you ovulate twice each month? Just curious, because most people would say it's impossible to ovulate more than once per cycle. There is, however, the possibility of ovulating more than one egg, especially if on fertility meds, but they all ovulate within 24 hours of each other.
