I don't belong here as I'm not pg anymore, but while I don't think you should be "alarmed", I think it calls for a moderate amount of concern. it could be your mucus plug, which could mean nothing, or could mean things are starting up a little earlier than they should. a trip to the m/w is a good idea. the fact that you have no cramping or contrax is comforting, but dark red blood at this stage is something to be looked into. good luck, it's probably nothing!
