I took 4 tests throughout the day I got my first BFP and they barely progressed within that day. I had to take a few days to see real progression. I can post pics if you want? It's the same tests you have. Also, those tests take A LOT LONGER than the normal time limit to get dark. My first test you couldn't even see the line in the time limit, and an hour later there was a DEFINITE line there. Then as I kept testing they'd show up a little sooner each time.
