I have been consistent with taking my pills throughout the pack but I was supposed to take my pill on Friday night but forgot to and had unprotected sex that night. I made it up and took it when I got up in the morning but it was still about 12 hours late. I took 2 pills that day and that was the end of my pack. I also had unprotected sex the second day of my placebo pills. What are the chances that I could be pregnant? I'm really worried and not sure how concerned I should be. Any advice would be wonderful. Thanks!
