Some women do "bleed/spot" during the first trimester when they would normal have there cycle, which would be about 5 weeks pregnant. It's very possible that you ovulated later that cycle and really are just 5 wks 5 days.
Try to relax and wait for another ultrasound and check the numbers. As long as the baby is growing there's always a chance!
I really hope everything turns out ok for both of you, It's very hard going through a miscarriage, and moving on.
