Girls, hi. When the traffic jam clears, do they definitely have to be blood clots? I haven't slept well all night and feel bad all day. Sometimes it hurts in my lower abdomen (the pain is tolerable and non-constant). I noticed discharge similar to a traffic jam, but there were no blood clots. Now I think about this could be labor signs or not.
