In brief: Probably not

It usually takes 1-2 pill cycles before your body gets used to the new hormones.
Make sure you take your pill as directed at about the same time every day. Smokers should not be on the pill (they are at increased risk of stroke, especially after 40 years old). Some pills have 24 active hormone pills, others have 21. This will affect when a woman starts her period after stopping the active hormone.
