I’m so confused!!

So I’m due for AF Monday. I tested when I was 7 dpo (early I know) and got a very faint positive. I tested every day since then and got all negatives so I was just about to give up for this month. Well I decided to test tonight and got this. What does this mean? Going from a faint positive to 3 negatives to another faint positive. Does this one even have color??
