Implantation bleeding or something totally different???

Kelsey • 👧🏼👼🏼👼🏼👼🏼👼🏼 Had my little girl that came early on 2-24-20! Now TTC #2 but 4 early MC in 2021 l 0 BFP in 2022😩. We will see if 2023 will be THE year. At least I’ve got my girl 👧🏼
I've been having light pink CM starting at six days past ovulation and it still happening today ...that makes it 5 days now...i've read that implantation bleeding only last up to three days but my period does not start until next weekend.   Any suggestions???
