Today im 9 or 11 dpo today at lunch time i went to the toilet and after i wiped there was brown discharge thinking AF came 4 days early i put a tampon in but when i pulled it out an hour later there wasnt much on it just a tiny bit of brown then i couldn't put a new one in so left it. Now when i wipe nothing there could it be implantation bleeding
