Is the hook affect real?

This sounds wild, but has anyone ever experienced the hook effect?

I was having positive tests (never got super dark but were dark enough) and at around 6 ish weeks I thought it was a chemical. They started going away.

Flash forward. I’d be almost 11 weeks. Still no period since august. Haven’t had sex since September. And I did a test for fun. And I think there may be a faint line?

My doctor is brushing me off saying blood tests and ultrasounds are a waste of resources and I’m not pregnant if I didn’t have a positive.. so I’ve been living my best life. She said I’m probably just late because I had covid 😬.

Do you see it? I’m not completely crazy right?
