Thank you for your query.
Firstly it is possible that the I pill
has interfered with your natural cycle.
I pill can prepone or delay your periods by a week or so.
However, I pill is never a substitute for a regular contraceptive
it is very simple that if you have missed your period, please take a home urine pregnancy
test tomorrow morning, so that you would know for sure that you are pregnant or not.
If the test is positive, please consult a gynecologist at the earliest for advice on termination.
Have protected sex in the future.
