is it normal ?

Carely
Heyy guys !! I have a quick question? 
Kind of embarrassed but if anyone might help me I would be so greatly appreciated!! 
A year ago I had a miscarriage and well after that I started to get my pereiod on a different schedule. And now since may I haven't gotten my period I only get it one day a month and just spot for not even an hr. I made a doctors appointment but I just want to know anyone's opinion or thoughts into what it is ?
