Ovulation Help

Hi ladies,

So, I am at a complete loss! I am new at figuring out when I will be ovulating using a test strip and according to Glow I was ovulating on the 26th of January but when I tested with the strip the line was there but faint, still visible but not a strong dark colour. I did some reading and every woman’s body is different obviously and it said if the line is clearly visible consider it as a positive result if there is no line it’s a negative, easy enough. But now I am 7dpo and there still is a line visible? I started tracking my ovulation on the 21st and I didn’t know when to stop so I just kept going. Well again today a visible line, is that normal? To have a positive ovulation reading that long?? I have attached a picture below. Thank you!
