I started on the Mono Nessa within the first 24 hours of my period, like the pack said. However, since this was on Wednesday, I took the first Wednesday pill (possibly incorrectly). The pack says to "take the first blue active pill of the first pack", which I think means the first Sunday pill? This would make sense if each week of pills had a different level of hormone in them, but would also defeat the purpose of the SUN / MON/ TUE labels.
For anyone who's used this type of birth control before, which pill should I have taken? Do birth control pills always have a different amount of hormone in them for different weeks, even if not labelled?
