Hi. I am a 21 years old girl and had unsafe sex yesterday night and it was my 5th day of period with no bleeding at all. I am suffering from pcos, but from the last two times, I am observing that my periods are occurring in a cycle of 41 days. However, it's not so every time. Also, I consumed an emergency contraceptive pill in march end. I don't want to get pregnant. What should I do? Should I take an emergency contraceptive pill again? Or will doing nothing will also work?
