Good night i have a friend she is about 9week pregnant but they cant fine a heartbeat and she do a blood test and it show she is still pregnant?

Not 9 weeks?: You should see a heart-beat at 9 weeks; however, its possible that your friend is really less than 9 weeks. Also, a single blood test won't clarify the situation. She needs two blood tests 48 hours apart to know if the the pregnancy hormone level is going up or down. There are gray areas where its hard to tell. In these cases, the ultrasound and bloodwork is repeated at another time.
