I was wondering if it was normal for my “period” to be delayed or missed while on the combination birth control pill. I’ve been taking the pill since October and it always comes on the hormone free week. What worries me is that I’m on the last two hormone free pills and I have yet to experience any bleeding. I take my pills consistently, like on the dot every day at 8:00 pm, so I’m using the pill correctly. I’m hoping that I’m not pregnant. Has anyone else experienced this? Should I be concerned?
