This is my 5th or 6th day after my periods and we think there had been a leakage in condom while intercourse, not sure though. We don't want a child now as we are not ready and wondering what we can do. Can I go for emergency pills like unwanted 72. This pill my wife had taken 2 months back. And if I take can it lead to infertility by taking 2 pills in the span of 2-3 months. What is the best way to avoid this at this stage.
