Thanks for your query.
Firstly, I must admonish you for the highly indiscriminate use of the I pill
It is not meant for popping casually the way you have taken them.
It is ONLY for emergency use , and not a replacement for a contraceptive
The Use of the I pill is the reason for your erratic periods.
Please consult a gynecologist to rule out pregnancy
, as there is no pattern to the periods, and you cannot rely on urine tests.
