If I possibly had implantation bleeding at 11pm on 12dpo when can I possibly get my bfp? I was supposed to start today at 15dpo and it is now 8:30pm and I have yet to start but had a bfn this morning with fmu. The possibly implantation bleed was a teeny tiny red spot of blood about the size of a pencil tip if that and I have had nothing but creamy cm since. So if y'all can just give me some ideas on how long it should possibly take to get enough hormone in my urine to show up I would greatly appreciate it! Thanks guys!
