Implantation or Something else

Sydney • Wife❤️Bonus Mom & Mom ❤️

So 8dpo ( guesstimate ) and have had super faint brown spotting the past few days but only when I do cm checks . Could this be implantation? We didn’t have much time for baby dance so it was the last day of my cycle. Not sure if we could have just gotten lucky this month. Thoughts guys?!!
