I've been on the for about a year. My boyfriend and I had sex without a condom, though he did pull out, this past Saturday. Starting yesterday, Weds., I noticed some pink when I wiped and then this morning it looked a bit like fresh red blood. I am a week and a half into my current BC pack. I've never missed a pill and take them religiously, I took two pills 1-2 hours late this last week due to starting work and forgetting to set my alarm for it. But I should still be protected even with the delay. Is this bleeding a sign of concern for me?
