The insert that comes with the pills gives specific instructions on what to do if you miss a certain number of pills in a row in certain weeks.
But i missed (as in took the pill much later than the time i'm supposed to) about 2 pills each week for the first three weeks but never missed them in a row. So I just would take the pill when I remembered and then take the next one at the normal time.

This is my first month on aviane and I'm on my last sugar pill and did not get a period. I am 100% sure I'm not pregnant because I have not had sex. But am I still protected against pregancy even though I did not get a period when I start the new pack tomorrow?
