OPK and HPT question

Brandii
So... I had a miscarriage on Feb 8th, I was 6 wks 6 days. I took both test and got a faint positive on both. Does this mean that my levels are not at zero? How could I get a faint line on the OPK... I shouldn't be ovulating yet, or is it possible? (I'm not TTC yet, I was just curious to know the results) my OB is not monitoring my levels but I was told to do lab work 21 days after my 1st cycle to check progesterone levels.
