BFP with first child. VFL now?

Lydia

With my first child I had a BFP. The line was darker than the control. We are TTC #2 and I just tested at 12 DPO. It was a VVVVVFL I actually didn’t even notice it. But my hub did. About 2 months ago I was pregnant and had a VFL but I ended up MC at 7 weeks (she said the sac was only around 5 weeks.) Does this mean this baby probably won’t stick either? :(
