Missed one pill

Patient: Hi.I am a regular yasmin 21 day pack pill user.I had sex on the 14th and realised right after that I had missed a pill for that day.I took this pill immediately and took the next one the following day as usual(this is during the 2nd week of the pack).I am very particular about taking my pills and have never missed one before.Please advice.It has since been 36 hours.Do i need to do anything more?
