In the begining of july my girl accidently started her birth control on inactive pills, (she did get her period at the begining of the july month)that would have her at 2weeks straight on inactive pills. Once realized she had taken the last placebo pill. She immediately started taking the active pill. She is never mixing up pills however she just started a new job so she was quite thrown off. now she is 7 days late, could she be pregnant? She takes Trinessa LO
