I am now on day 24 or a regular 28 day cycle ... on day 20 i found a watery dark brown clot (eek sorry TMI) - then day 22 in the evening there was more dark brown clots - not much that lasted yesterday and has now gone ... AF due on Saturday ... Ive read LOTS of posts and could it be ? .. could it actaully be implantation ? .. did anyone have this AND end up with a BFP? .. ive read lots of posts but most dont say whether it resulted in a BFP - look forward to hearing from you - been trying for 14 months now so at this point everything is crossed!!
