I had unprotected sex on 2nd September, when I was not fertile and took an emergency pill on 3rd September for the same. I was also prescribed three tablets for my UTI on September 3- Nifty, Urispas and Pyridium. I had a mild yeast infection too, so I started using candid v gel from 5th of September till 9th. My date for menstruation was 7 September, but I still have not got my periods. Don't exhibit/feel any signs of pregnancy, but I've not taken a pregnancy test yet.
