Has anyone used the 10imu tests?

I’m 6dpo and I just got these in the mail today so I just wanted to see how they work since I’ve never used one of the earlier prediction tests. Since ovulation I’ve had burning sensations in my nipples like you do when your milk comes in after birth, I’ve also had cramping and stabbing pains in my left hip since then. No IB or anything. Just curious if these always look like this? Or if anyone has used these before and what your outcome was? I feel like it’s just an evap line so I’m really not concerned with it being positive because I know it’s way too early to test. Also, I know you shouldn’t take the test apart but that doesn’t make it invalid if the result is already clear. I just couldn’t get a clear picture of it.
