Taking one too many contraceptive pills and menstrual delay: is this normal?

It is normal to experience a delay in your menstrual cycle after taking an extra contraceptive pill. This may happen if you have taken a hormone pill from a different pack. Taking an extra pill should not affect the effectiveness of your contraceptive, but it could potentially disrupt your cycle, causing your period to come earlier or later than expected. It is recommended to continue taking your pills at the same time each day and start a new pack the following Sunday to maintain contraceptive effectiveness. If you have any further questions, feel free to ask.
