Gray or blue?

Ashley • Hakuna Matata ✌️
My husband and I have been trying for two and a half years. I had to have surgery to remove a uterine septum. I've taken tests before but they have never even shown a glimpse of anything before. Today I took a test. I will admit I'm a few days early. I thought I was seeing signs of implantation bleeding. Shortly after ovulation I was having these, physical, feelings that maybe this is the month. But then those feelings went away. So I decided to test anyway. And I swear I see something. I can't tell if it's a faint blue or if it's just the gray line showing through.... Any insight would be appreciated!
