I have been on the combination pill, Junel FE for over a year now. I'm usually, always on time taking my pill at 11:30 every night. Twice, this month in week 1 and week 2 I took my pill 2-4 hours late because I had fallen asleep before my alarm went off to take my pill. I am now on day 4 of inactive pills and my period is still not here. I have taken a pregnancy test last Saturday, and this morning, and both were negative. I understand taking a pill late may decrease effectiveness. But, what are my chances since I have been testing negative?
