Yesterday around 5pm I noticed pink spotting. It didn't show just from wiping. I put a finger up in there and that's how I noticed the spotting. First time pink. Then Brown. Then pink then Brown again. I figured it was probably my monthly about to come on. Well here we are in the AM. Checked and figured if its my monthly coming then it would be heavier spotting or even bleeding by now. I wiped again nothing. Put my finger in and super light brown comes out. Could it be implantation or just my monthly being stubborn to come?
