Hello, I am starting to worry that I could possibly be pregnant. I should begin by saying that I am on birth control; Microgestin 1/20 Fe tablets to be exact. I have taken them since September. Prior to September, I had never taken any form of birth control before. My last period started on December 2. About 2 and a half weeks ago, I experienced some brown discharge. However, this break-through bleeding has occurred since I started taking the pill. I had protected sex (condom) on December 26, the last night of taking the regular pills. I am nearly positive that he did not even finish inside of me. I never got my period last week, which was the placebo week. I recall seeing an extremely small amount of blood when I wiped early on last Monday morning, 12/28 but other than that I had nothing. I have never gone the entire placebo week without getting even brown discharge. Additionally, I experienced some cramping and breast tenderness last week. Given my situation, does it seem possible that I could be pregnant?
