I am five weeks 4 days pregnant with my second child. This time I have experienced very little symptoms. I only have sore nipples and a missed period. No sickness, but the past week I started seeing a light pink sometimes dark blood when I wipe. Mild cramping, but I’m also constipated so that could be from gas build up. There really isn’t much blood at all, but it’s been more then one day that I’m seeing it. I have an appointment feb 24th but I plan on calling in the morning, should I be concerned?
