Thanks for your query.
Firstly, it is not advisable to consume I pill
so frequently and casually.
They tend to alter and mess up your normal menstrual cycle.
The i pill is the most probably reason for your earlier period.
The i pill, specially when taken within 3 hours, is effective, but no method is 100 % sure.
I would advise you to test for a pregnancy
, once you go past the date of your last expected period.
That is, after another 7 - 10 days, though the possibility is almost nil.
Please switch over to a reliable method of contraception
in the future.
