So I have been on Aubra birth control since January 2016 and have never missed a pill. However, yesterday I forgot the pill completely. I usually take my pill around 8-9 am. Today I took yesterday's pill and today's pill both at 11:45 am. It was over 48 hours since taking any pills, but very close to that range. It is my third week of the pack, 3 days before I begin my inactive pills/start my period. I only really missed one pill, but I took my normal one a bit late. Is it absolutely mandatory I use condoms/back up or should I be okay since the chemical was in my body for such a long time/ I am going to be on my period soon?
