Please help, please.

I took 3 pregnancy tests yesterday afternoon and all came out positive. No Evaps, certainly positive. Not blaring pink, but still positive. Today in the morning I took more tests and they are so faint, so much fainter than my tests yesterday! Plus, I took a digital and it says not pregnant. I am heartbroken. What is going on? Am I going to miscarry? Is this a chemical pregnancy? Please see pic. First test is from yesterday afternoon, second test below (the more faint one) is from this morning.
