Help ease my mind maybe?

I tested at 10 DPO immediately had a faint line, I’ve never seen a faint line on a test before let alone it staying on the test and having color. So here we are 4 days later at 14 dpo, my SO went to the store and got me more tests different brand and i just feel like the line isn’t getting any darker and it isn’t showing very well on camera. I feel like my y SO is getting annoyed with continuously looking at tests and me telling him there’s definitely something there and him bickering there’s not. Has anyone else had it this way and everything still turned out great, just a little worried right now.
