Ovulation Test Strips - faint line

Hey, I was wondering if I could get some healthy guidance and support. I’m trying to conceive for the first time and god it’s stressful. I originally said ‘if it happens it happens’, however now I’m completely obsessed with tracking my ovulation!

My app says I’m due to ovulate and I’ve been testing but the line is VERY faint and had been for the last 4 days (ovulation is meant to happen in 2 days). Im just concerned I’m stressing myself out and it won’t happen (even though this is my first time and I have no idea what my body will do). Any wisdom or guidance for this process would be appreciated. Thanks x
