The same thing happened to me last month. I got three (faintly) positive wondfo, and a negative FRER with the same pee as one of the positive. Then I got AF just a little late. It could be the wondfo were more sensitive, it could be a bad batch of wondfo. Either way, it's a huge drag!

In any event, that's why I'm going to do my best to not POAS until AF due date. I don't know if I will make it or not. I'm weak....
