Ninety-One-Day Birth Control Pills
Levonorgestrel/ethinyl estradiol (Seasonale)
These pills are monophasic birth control pills that have been approved for use on a daily basis for 84 days without interruption. Users have fewer scheduled menstrual cycles (only 1 period every 3 months). Data from clinical trials show that many women, especially in the first few cycles of use, have more unplanned bleeding and spotting between the expected menstrual periods than women taking conventional combination birth control pills.
