Q: I stopped the pill two months ago but am bleeding irregularly. What does this mean?
A: Your regular menstrual periods and your bleeding are generally controlled by ovulation. While on the pill, your ovulation is suppressed and your menstrual bleeding happens every 28 days because you are off the hormones. After stopping the pill, your body needs to readjust, and it may take several months for ovulation to return. Until you start ovulating again, you don't have a regular period. You may either not bleed at all (amenorrhea) or your vaginal bleeding may be irregular -- more often with shorter cycles (polymenorrhea) or less often with longer cycles (oligomenorrhea).
