What’s going on with my body 😓

Ok so I’ve been testing for 1 week and I’ve been getting vv faint positive in the last two days my lines looked like they were disappearing. today I tested in the am and there was nothing so I was like ok the other test were maybe defective. Me being me because I had one last test I used it and I get the faint line again well it looks darker than the last three I took 🙄🤦🏻‍♀️ what’s going on. I don’t know when I ovulated because I don’t keep track so this is just so weird 🤷🏻‍♀️
