I'm on TriNessa and have been taking it for several years. I started a new pack on Sunday and took my first three pills on time (which for me is at 10pm). On Wednesday, I had unprotected sex in the afternoon (I had taken my pill Tuesday night at the normal time). Wednesday night, after sex, I forgot my pill. I remembered it Thursday morning and took it at 8am (10 hours late). Am I at risk of getting pregnant because I had sex and then took a pill late in the first week of the pack? And should I use backup protection for the next week? Thank you!
