I have been spotting for about two weeks now but haven't had any cramps or clotty blood. Tonight I have been having clotty blood but no cramps, how ever I have a history of miscarriages and clotty blood concerns me. I'm trying to decide whether or not to go in to the ER and spend all the money just for an ultrasound when I have a doctor appointment this Tuesday. Has anyone had brown CLOTTY spotting with a little red blood and had baby still be okay, with baby's heart still beating?
