Anyone ever get a faulty digital test? I took a test this morning which I originally thought was the typical frer, but right as I was about to use it I noticed I grabbed the digital test from the box. I figured it would be fine either way, but right after I used it, it popped up with a question mark. I'd never seen that before. Glow says AF should have been five days ago but Ovia says she should have shown today.
