Late period 18dpo

N

Good day ladies.

Little background:

Started my period on 28 Sep

Ovulated late on 20 Oct - confirmed with :) and did the baby dance

Predicted to start my period on the 4 Nov

I am 4 days late… I took pregnancy tests and all I have gotten was bfn. I have only had a white discharge the past few days

Have ANY of you only gotten a bfp and successful pregnancy after 18dpo even if you tested negative before?

Baby dust to everyone that is TTC 🧚
