Progression lines 5w3d

I’ve been testing every other day since I got my BFP (on 4/1). I decided for some reason to test two days in a row and my line from today doesn’t look as dark. I peed on the stick yesterday but today I dipped the stick in a cup of pee. I also was more hydrated and it was midday today when I tested. What do y’all think? Just looking for some reassurance and anyone who’s had the same experience with a good outcome! I had a MC in Sept 2017, and my rainbow baby is 18 months old. Thanks in advance!!
