Is this normal?

According to Glow and my opks I ovulated on cd7 (Jan 1st) ( I only have a 5 day period), well like mine normally do the opk went back to negative that night, but I tested again the next day just to be sure and it came out positive! So then I thought well that can be normal too, so I decided to test until I got a negative, but I haven’t gotten a negative since, they have all been as dark or darker than the control line ever since cd7! Is that normal? I’m really confused.
