Anyone had BFN at 10dpo and still been pregnant?

So I’m currently 10dpo and got a bfn today.

Feeling really disappointed.

2 days ago I had some pink bleeding that lasted a few hours which I thought could be implantation bleeding, and AF isn’t due for between another 3-7 days (irregular cycles but ovulation pinpointed with opk and bbt).

Last night I had a bizarre dream that I had an unknown pregnancy and gave birth to twin boys.

I was talking to my niece today who told me she had a dream last night that I was pregnant and in her dream we went for a scan and it was twin boys too!

I know it’s just a crazy coincidence, but feeling hopeful that I’m not completely out until AF shows her ugly face...

Fingers crossed!
