False positives?

Georgia

Has anyone experienced false positives with Walmart .88 pregnancy test? I feel like they’re messing with me. One kinda had a dye run but was positive the other was so faint but looked positive, which got darker after 5mins(I know can’t read that) and the last I took today which I thought was negative at first but later did what the first did. Not sure what I’m doing wrong :( I ovulated on the 9th so it’s really early and my first time using these test. It’s the first I’ve gotten anything but I’m scared they’re all invalid?
