Hi, my name is Alexis and i need someone to hear my story. I am 19 and i need a little help. Im not sure what this little bit of bleeding is and what it means.....Implantation bleeding? Ovulation bleeding? Cysts? Im confused. 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? My period should start in a couple weeks if im not pregnant and my boyfriend and I do have unprotected sex.......help me please! i would appreciate it!
