I usually get my period at the end of every month lasting until the beginning of the
new month. My last period started the
18th of Dec. 2010 (which is werid because that is the
middle of the month) with unbearable cramps and heavy breathing that usually do not occur, but went on like a normal period but just slightly heavier. On Jan.1st, two weeks later, i noticed i gushed out some dark red blood mixed with a little white mucus and tissue about dime sized. what is this?
