Implantation??

Hey y’all! Currently in month 9 of TTC and I feel like a crazy person every month haha. My cycle is incredibly regular- ovulate on cd17 with a 14 day lp. My period is on time every darn month (of course!) and usually I start spotting the day before AF. Butttttt, this month I had some random spotting at 10dpo (4 days before AF). Really doesn’t even seem like spotting, more so light brown cm? And *TMI* but I only saw it when checking cp??

Thinking it’s probably just my body being weird as I have zero symptoms other than being slightly more emotional.. not even my normal PMS? AF is due to start in 3 days. What do you all think?? I know there isn’t really a way to tell until I get af or miss my period, but always love seeing what you all think! Keeping my fingers crossed that month 9 is the lucky one! 👼🏼
