I realize this is my stupid fault, but I never miss a pill and did so this month and now freaking out. In fact, I missed 2 pills in a row. I am actually in my 3rd week of my pack. I missed Friday and Saturday's pills, and then took 3 pills on Sunday. I then had unprotected sex on Sunday night, should I be worried about getting pregnant? Should I get the plan B pill today (Monday)?
