I am so scared

I am freaking out. Shaking! I just got a bfp. I am early, period was due in 2 days but got a positive on first response and also clear blue digital. I don’t have the greatest history…. First pregnancy resulted in a mid second trimester loss. Second pregnancy was successful. Third pregnancy was a chemical. Now this. I am so scared. I don’t want to let my heart believe it. My husband is still sleeping and doesn’t know. I got a negative test yesterday so was not expecting this. I am either 11 or 12 dpo. Please pray for a sticky baby! The line is faint so I am terrified it’s another chemical. I feel like it should be darker at this point…
