bleeding. HELP!!

Ki

i have been bleeding for almost a week and I'm just over 6 weeks pregnant. started out as spotting then became more. I had an appointment yesterday baby is there measuring 5wks 6days 3mm heart rate is 114. but during the exam they pulled a blood clot out and since then the bleeding has been heavier and more clots are coming out. should I be worried. my next appointment is in 2 weeks and the wait is horrible with this bleeding going on.
