Thanks for the query.
According to your history, the possibility of pregnancy
Because you are on contraceptive
And you are using them regularly.
Half an hour to one hour delay in intake of pill usually won't affect the efficacy.
If you miss the pill completely, then there is possibility of pregnancy.
And also contraceptive pills are having high protective rate.
So, no need to worry.
Wait till your expected date of bleeding. Possibly you will get withdrawal bleeding as expected.
And if you miss the periods, wait for 4 to 5 days and go for pregnancy test.
