Chemical?

I've been a crazy tester. I started testing at about 10 dpo and tested every day. I posted my tests In here multiple times and the line got a bit darker but unfortunately I'm on day 2 of missed period and the line looks light :(

Below I have posted tests from Feb 2nd, Feb 4th then from today Feb 6th. I'm thinking it's a chemical. :( TTC is not for the faint of heart. I'm going to take another break from it for now.

Update: 2/7 I went to the bathroom and there was some blood when I wiped. Have been having sharp pains in my stomach. It was a chemical. :(
