I had intercourse October 27 and 28 each time with a condom. I am on the birth control Orsythia and I have never missed a pill and I am also very careful to take it at the exact same time each day. I also suffer from generalized anxiety disorder so I have been in a constant state of stress thinking that I am pregnant. November 10, 8 days before my withdrawal bleed normally occurs I had very faint spotting, a little brownish/ light reddish in color. Could this spotting be due to excessive stress and worry?
