Is this implantation bleeding? Help x

Hi Ladies :-)

Sorry for posting graphic pics on here but I have nobody else to turn too.

My last proper period was 14th Nov & I was due again on 17th Dec but I had period a week early on the 10th Dec which wasn't as heavy as normal anyhow on the 23rd I started losing this? It was on & off from 23rd to 26th just wondering do u think it's ovulation or implantation? When i ovulate i do lose abit of blood on the actual day but never lost brown or lasted any longer than 1 day? Any advice? My next period is due 5th Jan x
