TMI but is this a miscarriage clot ?

Mackenzie

I was 7 days late on my period and had the faintest of faint lines on a pregnancy test - so faint you’d have to shine a light and squint . After being 7 days late and lots of cramping I got my period- relatively heavy , but just passed this clot with greyish tissue at the end of the period cycle . Was this really a chemical pregnancy / miscarriage ?
