I am currently 14 weeks pregnant. For the past three days I have been bleeding brownish and light pink blood. I went to the hospital and had an ultrasound, only to find a fetal pole of 4.40 cm, which means I am 9 weeks and 3 days according to the doctor's calculations. I need to return in seven days to check if the fetus is growing. Anyone who has experienced this situation, please help.
