You are on Yasmin 28, take all the 3 weeks of pills like you should but decides to skip placebo week for whatever reason and continue on the next chart of hormone pills instead. In the middle of what should have been your placebo week, you miss a hormone pill. What happens? Is the safety compromised because you missed a pill, or is it OK because, seeing as it's your placebo week, you should be fine for an entire week without pills?
This is just a hypothetical question I was thinking about earlier.
