What is happening...

I got a vfl 3 days ago and I got really light pink discharge *insert picture 14dpo*

Next morning I wake up and its red now

Now I’m thinking this is af obviously right

Weird thing is I am a very heavy bleeder and it was heavy one day and now it looks like this

Getting lighter and lighter. Which is definitely not normal for me

Could someone explain? Am I pregnant? False alarm?
