Nervous about line progression!

M

You can tell me 100 times ‘a lines a line’ but after a chemical and a missed miscarriage I’m obsessed with that little line getting darker. I’m curious to know why today’s isn’t as dark as yesterday’s.. I did have a little water to drink before bed last night 🤔 and the control line also looks skinny so maybe it’s just the test? Either way I’ll now not test for a couple of days so I don’t drive myself insane!! Left is today’s, right is yesterday.
