How does this keep happening???

Anna

I just got a faint, but obvious positive on a FRER. I’m due for AF today according to Glow, but I’ve taken my pill damn bear perfectly, and I’ve got two pills left. I’ve suspected I was pregnant for about two weeks. I also took a Walmart test, and it is flat negative. Any thoughts or suggestions? Here are pictures, but taken within the respective timeframe of the test.
