First Repsonse vs Clearblue Digital

Amelia

I took a First Response this morning and there was a vvfl. I took a Clearblue Digital after that and it came back as Not Pregnant😩 I’ve been TTC 10 months and I’ve never had any sort of line show up, so I’m confused about the Digital results. Is this normal? I’m between 9 and 11 dpo. Thanks!
