My girlfriend and i had protected sex 3 times in a row last january 3, 2011. her last menstrual period was last december 19, 2010. yesterday january 8, 2011 he noticed that there was a blood followed when she urinated she described it as kinda brown in color, a day before that she had cervical mucus and on the day that she saw the brownish blood stuff with her urine her cervical mucus was just minimal to none. She didnt also noticed any blood when she wiped her vagina. since then she didnt noticed the brownish stuff.. is she pregnant?
