Should be 7w3d dr said would guess around 5 or 6???

Yesterday I had some brownish discharge and then today more of a pink discharge. I called my dr and they had me get blood work to measure my HCG and to come in for an appointment this afternoon. I should be 7w 3d but after the dr did the ultrasound he said he would guess only five or six weeks. My HCG Level was 6800. The dr said he thinks everything is fine and scheduled me for another ultrasound in 10 days. I know when I would have conceived because my DH and I were not as active as usual due to some changes going on in our home. After reading others stories I am worried that the baby just stopped growing early on and I will eventually miscarry. Has anyone experienced this?
