I take tri sprintec. I missed an active pill, then took my next pill 12 hours late. (So total I went 36 hours without a pill). I took 2 after the 36 hours and then 2 the next day and am finishing my pack. I was on week 2 of my pills. Do I need to take plan B?
Hi, The effectiveness of birth control pills goes down with missing doses, and it has a significant failure rate anyway. Plan B is only for about a 48 hr window after intercourse. So, it is an indication for it, but it might be too late by now. Hope I have answered your query. Let me know if I can assist you further.
