If your cycle is 28 days, you will ovulate 14 days to your next menses. You should also note that the day 1 of your cycle is the first day of your period.
If you see your menses on today being 5th of June for example, today is your day 1, going with the 28 day cycle, you are expected to see your period again on 2nd of July. Your ovulation period will be on 19th of June.
If this is clear, your fertile period is 3 days before your ovulation, your ovulation day and 3 days after your ovulation.
You can also use the kangpe cycle planner, it's simple to use. Just insert your data and you are good to go. Take care
