Pregnant again...?

Li

So this morning I took a pregnancy test and it was faint, but positive. I was supposed to get my period today but began running a fever- which is my tell tale pregnancy sign. I took another test this afternoon to be sure and it was negative. Do you think my test this morning was wrong or just that my urine this afternoon was too diluted? I took a FR rapid results if that matters.

PS I very well could be pregnant, as I’m we were not trying to prevent it. I just don’t know which to believe and was looking for other people’s experiences.
