Screening Test Results - Bad News?

I'm in the low risk for the first two but in the second letter they're not clearly told me what the problem is.

I can only assume its the PAPP-A test 🤷🏻‍♂️

I've heard that PAPP-A can be linked to Down Syndrome but that doesn't seem to be the case here.

Is it a low risk high risk pregnancy or what?

Can someone tell me what this means? I feel like they're not quite explaining things.

Edit

I've been certain my due date was the 1st of April since I only had sex once that month. (after two years of trying).

But they said I was two weeks out?!

Could that be an explanation? Could my baby be small?

Was are the risks?

I'm not as worried as I make out at this point. I'd just rather know than be left in the dark which is anyone me more than anything.
