I’m so confused and frustrated! 2 different results?

Alison • Pregnant with baby #2 after weight loss surgery and depo! Baby Ellah Rae due 3/28/19 💗

I am 3 days away from AF and have been getting steady faint positives, I took both a digital and regular FRER just now and the regular is positive and my digital says no! Why is this?! I’m agonizing over here 😭😭😭
