thank you for the query.
The I pill is not a substitute for regular contraceptive
use, because the I pill can alter the bleeding pattern of your menstrual cycle.
It is most probably the reason for your irregular spotting between periods
However, the I pill can also delay your period by a week or more.
If your test result was negative, you can wait for a few more days.
If period does not occur, please consult a gynecologist.
Stress , anxiety, thyroid
disorders, polycystic ovaries
could also alter the normal pattern of your bleeding.
