Hi, I have been taking the pill for about 2 yrs. I had sex (with condom) after taking the pill regularly (couple hrs off sometimes) and then 3 days later I missed a pill and then the next day I took both pills. The next day I got confused and took the pill for that day and also the next day, then skipped the day of the pill I had already taken. This was the second week of the pack. I am now experiencing a bit of spotting and breast tenderness. Should I be worried?
