Is it normal for my test to be lighter the next day?

Br

I️ took the top two yesterday afternoon! The pink was the first one, and the bottom was this morning. Every time I️ took a test, it took forever for a positive line to show up, this is my tests around the 3 min mark, and then the more dark one on the bottom is taken around 10 mins. Now it’s more evened out but should I️ be concerned that it took that long to get dark? It also looks like the tests from yesterday are more faded now that they’re dry, is that normal? I️ hate to be this paranoid, but this hasn’t happened before with my previous pregnancies.
