Needing Help :):)

Hey all, I'm 24 ttc baby number 1 for 4mnths with my amazing boyfriend after coming off one shit of depo (doctor made a bad recommendation) but periods have been regular since first month of coming off.

So Glow says my fertile window was from 6th-12th of Sep, with my highest chance of being able to conceive on the 10th(my daddy's anniversary). My CM confirmed this.

And today I've had light spotting, could this be implantation bleeding? Or am I being a crazy baby lady? Thinking maybe my daddy was sprinkling some baby dust from heaven maybe...
