Sorry y'all ... but help

Congrats to everyone .!

But

Has Anyone gotten a bfn past 16dpo then get a late bfp???

I'm I out and just waiting on af to show??

Af suppose to come Friday. (Which is 18dpo)

I feel out but in also.

Should I still test or what for af??

I had some bleeding on Sunday... I hope it was implantation only saw it when I checked cm and lasted one day.

Im 16dpo now and got a faint line but when test dried it disappeared so I'm saying it's negative.
