So bummed out right now........

So I took two wondfos 2 mornings ago and got 2 faint positives and that evening, my wondfos looked almost negative. Yesterday morning, I took 3 more and they looked the same as the previous morning almost. Then some faint lines lastnight. Then this morning, took 3 more and they looked much darker and came up faster than the past 2 days. So my sister in law, who's a nurse, suggested a digital and it was negative. Now this evening, my tests aren't as dark as this morning. What gives man? Every time we get our hopes up, it doesn't work out. I can't even get my af regulated :( my last one was April 16th.... I'm so sad right now. My little girl said "mama when you loose all hope, it's gonna happen." But I can't loose hope, it's all I have.
