Am I crazy?? (See photo) (update)

I'm so nervous because I miscarried back in October around 5/6 weeks along. My period is due today and I got a BFP yesterday. I also tested this morning (I had peed throughout the night FYI) and I swear it seems lighter and I feel less pregnant (if that's even possible this early) but am I crazy?? The photo shows the first test on top and the second from this morning. I know my
mind could be messing with me since we've been trying for so long and have had 2 chemicals but isn't it supposed to stay the same or get darker? Thanks for listening!!
