I've seen people posting about IB or early AF, but what i have had is a bit different. LOL Only i could be different. At 7dpo i noticed (tmi alert) a tiny red speck of a dot in my CM in my knickers, just one little speck it was so tiny but of course i noticed it as i was inspecting my CM like you do. At 8dpo i noticed 2 tiny red specks in my CM. Again tiny little specks but noticed them as they were red against my creamy CM? Today at 9dpo i wore coloured knickers so i couldn't tell if there was any in my CM today. LOL what a stupid choice of colour that was today when i have serious checking work to do. Anyone else had this? I don't know whether this is what you would call IB or not, have no idea.
