Hello, I had sex three days ago. I have been diagnosed with PCOS. I started my first pack of Vestura. I did not take the first two weeks of the pills regularly. I may have gone 5 or more days without taking it. I had a 5 day period. I took the last five active pills very regularly (to the minute). I had dark brown spotting. I had sex, unprotected for 45 seconds, then we put a condom on and finished. Should I take an EC? It has been 48 hours
