I have recently discovered an oral contraceptive that allows us to have only 4 periods per year rather than 13. This is great for me because to control my periods I used to just skip the 4th week in the 28wk pack and move on to a new pack to avoid having a period when I didnt want one. The way this oral contraceptive works is the pack comes with 91 pills(84 active and 7 placebo). You take 1 pink pill each day for 84 days and then take 1 white pill each day for seven days. During the week you are taking the white pills that is when you get your period. Isn't this great? What do you girls think?? Oh by the way with insurance it is about $35 without it is $100 or so.
