I recently had a baby (5 months ago) and just started having my first period. It started out just spotting but has gradually increased (as usual.) Yesterday I had 3 blood clots but they were not the usual dark red, they were part white too. Could it be a miscarriage? Or just part of my uterine tissues? I've never had blood clots during my period so they were a new thing anyways. But I have never seen/heard of white/red clots unless it was a miscarriage.
