I took my first pill of the pack yesterday, however I went on a night out so took it at 1am instead of 8pm like I usually do. My app says I’m protected but I’ve heard some people say it’s not always accurate. Do I need to take extra precautions this week?

If you take your pill in your usage window then you are always fully protected.

Unless you are on a 3 hour desogestrel mini pill you're still protected because that's only 5 hours late
