Delayed Period After Birth Control: What to Expect

Question
Ok. I have been on the pill Gynera from the 29th Nov. my first packet stop on the 19th December. That four days and I have not seen my period yet. I was on these pills before and I would get my period with in two days... Is it normal for my period to take so long to come? and with in seven days if it does not come do I start taking the second packet?

Answer
It's unusual that your period wouldn't come 4 days after stopping the active pills.  If it doesn't come by 7 days, I'd do a pregnancy test.  As long as it's negative, I would start taking the second packet.  Sometimes women don't get a period on the pill.
