Positive or am I crazy?

I had the Essure procedure done 3 years ago after having my 4th baby. A few days ago I started feeling every single early pregnancy symptom, I’m pretty good at reading my body. So I tested and got a faint positive that darkened over time, but is still pretty faint. Keep in mind at the time I was 11 days out from my period and today I’m 6 days out. Can you guys help? I feel absolutely insane although I have read thousands of stories of successful pregnancies and beautiful essure babies. I’m still worried. I have taken an abundance of tests, 13 to be exact and this what they all looked like. This is just a variety from first test to today. Thoughts?
