10dpo brown discharge

10dpo. When checking my cervix, I came out with the TINIEST bit of brown discharge. Such a tiny amount that I wouldn’t have noticed if I weren’t hyper aware of everything. Could it be implantation? (Yes, I know it’s rare.) Or is it more likely to be old blood making its way downtown because my period is due in 4 days?

Edit: This WAS implantation. I was pregnant. Updating because I wish more people would update these kinds of posts! 😜
