Is my girlfriend pregnant? Need people with the best knowledge to answer!!?

I cant give you a yes or no answer. all she can really do is take another test or go visit her gynocologist. but if she is having slight bleeding with no cramps, and thats abnormal for her, she might be pregnant because that sounds like implantation bleeding (when a fertilized egg implants in the uterus to begin development of a fetus.) but like i said, instead of playing the guessing game, she just needs to take another test or two (tell her to take them with the first urine of the day)
