Positive First Response but negative digital

Ruth • Mommy to Summer & Sabrina 💕

I am 9 days late today and have taken a first response the last three mornings, and this morning I got a faint line. I got anxious and decided to take a digital clear blue at work just a couple hours later which was negative. I had bloodwork done today to check levels but will not know anything until maybe Monday. I am worried, has this happened to anyone? Here’s the picture of the faint positive first response.
