16dpo and neg

Kaden 👦💙 2017. ttc #2

Hi all today is 16dpo (got my peak at cd18 at 8pm then temp confirmed O at cd20) and still bfn. So heart broken cos i just want a bfp by now at 16 days past O day or just the witch to show up so i can start over. Here my peak. What do u all think? Anyone got a bfp later than 16dpo? Thank you so much
