Me and my boyfriend have been having unprotected sex and my boyfriend has been ejaculating inside me,however its now been a week and a few days since we last had unprotected sex and my boobs have been really sore and they feel bruised and swolen when i walk down the stairs i have to hold them it hurts that much.. this has only been going on for three days now also today i've had a light amount of blood and it really hurts when i wee. My wee is strong and i've also been having alot of vaginal discharge also been having cramping now and then,please tell me how likely the chances are of me being pregnant??? i would much appreciate it:-)
