how reliable is this thing 😭😭

Yasmine • TTC baby #1 with PCOS 💘
I KNOW it's blue dye, i wanted to try it because I have tested with the First Response but I keep seeing phantom lines! So I'm exactly one week late today and this is what I got? My question is HOW reliable is this test? Taking another tomorrow morning but would still love the advice! Thank you ❤️
