When do you really count the first day of your period ? ex. may 26 and next period date june 27th i counted 33 but period .calculator counts 32
A doctor has provided 1 answer
32...: You count the first day of your period as day 1 - so your cycle length for that month was 32 days (ending on June 26). June 27 was day 1 again...
