Miscarriage, positive pregnancy test?

Hi. I had a chemical miscarriage at 5.5 weeks. I did a pregnancy test last week (4weeks to the day I had a miscarriage) and it was positive. Does it mean I am pregnant or should I wait a couple more weeks. How long does it take for the HCG hormone to leave your body? What are the chances of a recurrent miscarriage?  

It may take up to 6 weeks for HCG to leave your body after a normal pregnancy but less than that after an early miscarriage.

Could you be pregnant again?

Recurrence of miscarriage is no more likely than last time .

I suggest you repeat the test again in a week if you still dont get your  period.
