Possible VVVVF + before implantation dip and spotting?

Good morning friends!

This is going to sound crazy, but do y’all think it’s possible to see a super, very, incredibly faint positive before you get a temp dip and brief spotting?

The reason I ask: I’ve recently read that the implantation “dip” is due to a surge of estrogen after the fetus finished implanting.

Last night, I POAS (because it’s a compulsion lol) and both hubby and I saw a faint, faint, FAINT line - like, a real squinter. Talk about line eyes after that!

Today - 11 DPO (could be 10), early this morning I had a big temp dip, and a little later, pale pink egg white-like CM.

If the dip occurs because of the estrogen surge after the egg implants, it makes sense that it’s possible to have some hcg in your system before the spotting and dip happens?!

I know it’s most likely AF on her way - but hope springs eternal, amiright?

Anyway, thanks for reading, ladies!
