I began this birhcontrol 3 months ago for my upcoming wedding. I have never been on birthcontrol before and I have never had sexual intercourse. The first 2 months on this drug I had intermittent bleeding and my periods were longer than normal. My Physician said this was fine as long as there was a pattern, this month I started bleeding 2 weeks before I was suppose to and I am not sure yet if it is just spotting or actually a period. My wedding is next week, how can I be certain that I am not going to get pregnant and that the pill is working the way it is suppose to? Do I need to use another form of birth control on my honeymoon?
