Pleas help calm my fears... but be honest with me 😞

So I have been getting really good progression on my first response tests the past few days but today I took another one and it’s lighter!! And also the lines are off center AND the control line is wat thicker with ink than any of my other ones... what’s going on? Do you think this is a chemical? My new test from today is on the bottom

I was totally freaking out so I took a cheapie too and the cheapie was darker than my first response!! Ugh!! What’s going on? Is this a chemical?

UPDATE!!! It was a faulty test last night!! It’s super positive!! Omg 💕♥️😭🥰❤️🌈
