Hello doctor, I had done intercourse on my first day of periods which is 3rd jan 2021 my friend used double condom but I was not sure that he used it properly or not so I took unwanted 72 pills after 2 hours of intercourse. After taking the pills my bleeding was very low and then today I had felt slight pain at my back. My menstrual cycle is of 27- 28 days. So in this case is there any chance of pregnancy?
