Is this positive?

Katelyn • Two 👼🏻👼🏻 in Heaven, 🌈 due 3/31/22
The test line is always faint on my OPK tests, so I am unsure of whether or not I'm actually ovulating. Does it have to be dark to be positive? My cycle is irregular so I start testing the first day my BBT spike, but they all look like this. This is my second month using OPK.
