    For women having regular periods with either a 28-, 30-, or 32-day cycle, as long as you have a regular cycle, you can deduct 14 days before your cycle ends, plus or minus two days, to estimate ovulation
    For example, if you are on 32-day cycle, deduct 14 days, and you will have 18, plus or minus two days. Therefore, you can deduce that you are ovulating from day 16 of your cycle to day 20. This means it is possible for you to become pregnant at this point in your cycle.

    For women having irregular periods, it will take a lot longer to calculate, and usually it requires a minimum of six months before you can calculate your ovulation period
    The first step is to tally the number of days your menstrual cycle lasts for six months. Then you can look for the minimum number of days your periods lasted, and the maximum days it lasted. Then, deduct 18 days from the minimum days and deduct 11 days from the maximum days, and you will have your range of your ovulation period. For example, if you have 26 days for your minimum cycle, deduct 18 days from it and you will have eight, and if you have 30 days as your maximum cycle, deduct 11 days from it and you will have 19. That means that ovulation may be taking place between the eighth day and the 19th day of your cycle.
