Altering cycle of my period using birth control

Ask The Doctor > Questions & Answers > Altering cycle of my period using birth control

Patient: If i were to stop taking my active birth control pill a day earlier (not take my 21st active pill) to alter my cycle by a day, would there be any negative side effects?

Symptoms: No symptoms

Doctor: Hello, thanks for contacting askthedoctor.comAn oc -pill pack is formulated based on a standard 28 day cycle of a l ady . so even if you miss your 21st day pill , your withdrawal would occur in next 7 days and then a fresh pack have to be started from day 1 of next cycle.Unlikely there would be any side effects per se and there would be no change n the cycle either, but you would stand unprotected early by a day.i hope i have answered your query,regards
