Clear blue digital test wrong?

S🌸 • Mama to a beautiful baby girl 🎀

Have any of you ladies had a clear blue digital test be wrong? I took one a couple days ago and it came back positive 1-2 weeks! But when I added it to nurture it says im suppose to be 3.5 I'm worried that maybe it means I'll have another miscarriage.. :( has this happened to you?
