I had sex on 10/18 (i missed a bc pill), 10/21, and 10/27. I missed 1 birth control pill in Week 11 (- 84 active pills, 7 inactive pills but we used a condom; I remembered and took it 24 hours later. I am now in the middle of my inactive (period) pills and have a light to non existent period. I also have no cramps at all.
