Could this be a BFP?

Molly • Soon we'll have 2 under 2!
I took a test this morning and I see the faintest second line. Should I retest again later today or tomorrow? I know it is SUPER light. My period is due Friday. I have an X-ray tomorrow for a check up from when I broke my neck and I would like to know if we're pregnant before then. Thoughts?
Baby dust to all!! ✨🍼✨🍼
