I’m confused?? HELP

Abbey

I just made a post resent today asking for help so read that please first for more details. Now I’m confused. So again I’ve been late on my period for 8 days now was supposed to start dec 22nd. (Read more info on last post PLEASE) the first one I took December 28th at night (didn’t realize you’re supposed to take in the morning.) came out negative. The next morning I took it out and just wanted to see and it now has a really light line showing behind it to make it a positive sign. Instantly got a panic attack because it says pregnant. I took another now this morning December 30th and is straight negative. Also on the box it says “Read pregnancy test within 10 minutes for answer. Disregard any changes.” So idk what to think someone help. I’m gonna continue to take them the next couple days or until I get my period. Fingers crossed please I do
