If I have been taking the contraceptive pill for a few years and for a few months now my period has been coming on Thursday instead of Wednesday

Hello,

It is completely normal for your period to not always come on the exact same day, even if you are using the pill. So there is no need to worry!

If your period is more than 3-4 days late and you are usually very regular, a pregnancy test should be done. Delayed periods or even the absence of periods from time to time is not worrisome, it is usually due to different causes such as a change in physical activity, stress, etc.
