I know guys this is totally tmi and I am sorry but I just don’t understand what’s going on with my body! AF was supposed to start today, but this brown spotting started on Tuesday this week! It’s been very light just like this! I can have the tampon in for 6-7 hours and this is what comes out. With my normal af I have to change my tampon every 4 hours and it’s completely full. Could this have been implantation? Would it last this long? Please help me understand.
