Now moving on to how long does it take to ovulate; the general answer is that you start to ovulate about 14 days after the last day of your menstrual cycle. The exact time for every individual is determined by the individual luteal phase. Luteal phase is yet another time period in the womenâs calendar which lasts for about 12-16 days and determines that how long does it take to ovulate for you. Once you find out the length of your luteal phase, subtract the number of the days from the time period between your two menstrual cycles.
The Association estimates that ovulation occurs anywhere between 11-21 days after the first day of your last menstrual period (LMP), or 12-16 days from when you expect the next menstrual period to start. Order a Fertility Kit or Monitor.
