Positive and a negative on a digital - Has this happened to anyone?

Ashley

I got a positive and then a negative on a CB Digital and now I am extremely confused. Has this happened to anyone else? Can you get false positives on a digital? This was yesterday at 11 DPO. The positive came first and then the negative after, idk if that matters. I just want to know if I’m pregnant or if this is a bad sign 😭 🤕
