It's a book but I need advice. Please!

I had a d&c in May because i miscarried at 11 weeks. I got my period in the beginning of July. My cycle was 30 days then after my d&c it went to 32-33. In October my period started exactly 30 days since my previous period. So I thought my cycle was getting back on track. Well October to November and November to December it was 32 days. December to January it was 30 days. Here's the part I need advice on. 
I always test 4 days before my period if it was to be a 30 day cycle. I tested Friday and it was negative but when I wiped it was spotting. It got heavier throughout the day and then was over this morning for the most part. Should I consider that an early period even tho it's 5-8 days early or implantation?
