I did but it came back negative
lemme tell you this, if your doctor says 'bleeding/spotting during pregnancy is fine' is full of crock, and you need to find a new doctor. i spotted throughout my pregnancy and my stupid doc at the time kept saying 'it's normal but not normal too. as long as your not bleeding heavily and cramping, nothing to worry about'. because i listened to that stupid doctor, i lost my baby.
have you taken a pregnancy test? if so, it just might be implanting blood
