I started taking trinessa 3 months ago (after my son was born) and have taken the pills every morning. I started my last two periods on time but this month I am on day 5 of the placebo pills and still nothing, other than mild period back pain. I am worried because my husband and I were sexually active this month. I had to be off the pill for almost a year before my other two pregnancies but am worried because I haven't started and do not want to be pregnant at this time (hence taking my pill faithfully)... Am I over reacting or should I be worried. What should I do?
