Does faint line at 12 DPO means risky?

CK80

I have a very faint line and I think I am 12 DPO. It’s not my first pregnancy and normally I got these faint lines at 9 DPO, and by 12 DPO, they were pretty obvious...... No photo, as there’s obviously a vvf line...

Can it mean it’s likely a chemical, or low likelihood of sticking?

Pray for me please.....

Thank you.
