Very confused

So I've been getting negative on all the opk's I've taken. I took a test this morning and the 2nd line did look darker then previous days and I was told to take another test in the afternoon......and these is what happened!!!!​the top is the morning test and the bottom is the afternoon test!! I also now have a uti (urinary tract infection) will that make any difference? And do I count myself out for this month??
