DID I HAVE A MISCARRIAGE?

Monique
A few months ago I thought I had a miscarriage. Is it too late to go to a doctor and confirm this? I would have done this earlier but I thought I didn't care and I got a new doctor who didn't really understand what j was saying (she thought I meant I was pregnant at that time). 
EDIT: when I say misscarriage I mean a very early one like I would have been maybe four - six weeks
