Thanks for your query.
During the reproductive age group , the commonest possibility with altered bleeding pattern is pregnancy.
THe i pill commonly causes some kind of bleeding within few days of taking it, but it is not the rule.
The I pill can delay or prepone your periods by a week or 10 days, so be prepared for this.
If you do not have your period 4 weeks after taking the I pill, please take a pregnancy test.
Anxiety, stress, travelling, weight changes , hormonal medications - all can cause an abnormal period.
, thyroid dysfunction
, adrenal disorder
, endometrial hyperplasia
, - all could be reasons also.
