Can anyone tell me or give me any hints on what you think of this? Period started on the 28/11/14 and I finished on the 3/12/14. When I went to the toliet on the 15/12/14 and wiped this was on the tissue sorry if it's gross or tmi just wondering if maybe it could be implantion bleeding? We have sex every 2 days from the day I finish period. Thanks for any replies.
