Sorry tmi

Not sure if this is implantation bleeding or maybe the start of af. I started spotting on n off again for the past 2 days. The first day only once when i wiped. The second day it went from really light pink to brown and also was only when i wipe, and it only happened in the early morning and late at night. I havent spotted all day today until just now and it looked like this. I havent gotten a period yet and since im irregular im not exactly sure when its gonna show up. Im trying really hard not to get my hopes up since weve been trying since my mc last aug
