I have been on the pill for not even 2 months now. The first month went great, everything went as it was supposed to. my first period on the pill was from Sept 15-21. My boyfriend and i had sex on the 23. I missed a pill on the 24, and took 2 pills on the 25. It is now the 3rd of Oct, 9 days before I am to start my period, and I am spotting dark brown. Yesterday it was less noticible, but today it's bad. My boobs have been hurting for about a week now. Could i be pregnant?
