Counting Question

[akrab]

OK I know when counting cycle days you count the day of AF as one.... so I O'd I believe on the 14th day going by cf and other symptoms ( I am not charting or using any pee sticks) I just mark day of AF count the days and mark the sex days... anyways so if I did O on the 14th day (June 17th) do I count that day as day 1? or do I count the next day as day 1... am I 8 dpo or 9dpo.... AF should be here July 1st if I have another 28 day cycle.... so 6 more days to go UGH
