Honey you didn't trick yourself, we all saw the line too, it's almost impossible to get false positives, especially more than one it sounds like u had an early miscarriage
This.
I didnt include it in my previous post because I didnt want to stress you out and it wasnt really relevent. But your experience sounds very similar to mine-
BFP on the Friday
Loads of symptoms
Started bleeding Mon (4 days after AF was due)
2 pee tests at the doctors were neg
Tues did a FRER which came up as a very faint positive.

I havent gone back for the bt results yet. But I already know the answer so Im not really feeling like I need to do it right away. Its just a formality now.

You didnt invent those symptoms. They were real. You were pregnant even if it was only for a short amount of time and it is more than ok to grieve your loss. Please dont bottle it up.
Loads of gentle hugs and love coming your way. We're all here to listen if you need to talk.
