I have a subchorionic hematoma that started a week and a half ago with bright red bleeding. The red blood only lasted a very short time and then turned into brown spotting and eventually stopped. I have had an ultrasound as recent as Friday that still showed the bleed area and that the baby is doing fine. For some reason though, for the past three days I have been spotting brown again. Should I be very worried about this? Does it mean things aren't going well or is this pretty common? Right now I'm at 12 weeks which is closer to a point that I could stop worrying about miscarriage but now I'm not sure if that still applies.
