I'm on either 11 or 12 dpo, due on in 4 days. Had BFN yesterday so 10/11 dpo... anyone else gone on to have a BFP? I have a 28-29 day cycle, tested with frer and feel like there should have been a line by now? I guess unless implantation didn't happen till dpo 10? Might be clutching at straws here!!
