Positive First Response Negative Digital Clearblue

Chelsey

I’m so confused I have taken 20 first response tests all which have a faint line but took 3 digital clearblues all with in a week and all negative. Last period was December 8th. Had spotting for 3 days right when last period was due on 1/8. My periods always last 5 days. Anyone dealt with anything similar? Hoping I’m pregnant ttc for 10 years never even had a faint positive before these.
