So I end my white pill on a Thursday, and then start the brown pills on that Friday. I always get my period Saturday morning. It is Monday morning and I havent started yet. I decided not to take my brown pills this month, but I didnt think it would make a difference because they are basically reminder pills. I take my birth control pills everyday... but am bad about not taking it on time everyday. My boyfriend always pulls out but we don't use protection. I have felt like I am about to start my period... I have been moody, and have had extremely slight cramps, and lower back pain, but no period. Should I be worried??
