I am currently two and a half weeks into my birth control pack and have 6 more days till i start my placebo week. I started birth control last month and this is my second month on it. When starting my second pack, I missed a pill in the first week, but i took it the next day and have been generally taking it at the same time every day, and if i don't its only off by a few hours. However, I had unprotected sex about a week into the back. I didn't take plan b, and now i am having spotting/cramping (it happened last month but it was much worse). Could i be pregnant?
