On novynette bc pills. ..i delayed my period which was expected last saturday however I am now getting a light brown discharge is that normal?

How. Did u delay ur period by taking more active pills from a second package? R u still taking active pills now? Sometimes this works to delay a period but will only do so for so long. This is similiar to the way the extended cycle oral contraceptives work and some break through bleeding is common on them especially in the first package. It varies from woman to woman and pill to pill how long u can delay.
That is breakthrough. Spotting. Tou needn't worry. That is the result of delaying the bleeding, which is a little less that 100%successful.
