Faint line... Digital test

Took these test today. There's a faint line in the first picture but the digital test says pregnant. I'm worried the test with the 2 lines isn't darker like others I've seen. My period is supposed to arrive in 2 days. I had a miscarriage at 5 weeks on Oct 2019 and been trying for our 🌈 since May 2020. Please stick 🙏
