Anna

hello i have a question. i Take the Pille to avoid pregnency. i Take 21 pills and then Pause for 7days to get my Menstruation.

my question is... normally my period would begin tomorrow (i took the 21th Pill Yesterday) and i want to ask can i Take one Pill from the Sheet for the next month to get my period one day later, because i have an importantly apointment tomorrow where i cant have my period.

for the next month ID have one Pill less. that means that i d geht my period then one day earlier.

can i do this and and would the Pill work Like IT Always did
