Help! Positive now pretty much negative test

Rebecca • Mummy to Isabella Grace. Expecting baby number 2, 23rd March 2023 ❤️

So I should be 4+4 today but took my last tests this morning and it’s nearly negative. Is it a chemical? I’ve had no bleeding, but had had headaches so wondered if that’s my hormone dropping. The first positive I got wasn’t even that dark, so I’ve been concerned!

This is today’s test-

Barely can be seen! My husband couldn’t really see it 😭 just after we bloody told my parents as well 👍🏼
