I've been sick all week and now I think I either have a uti/bladder infection or a kidney infection. I've been cramping for almost 2 weeks, but since last night I feel this pressure and like I have to pee every few minutes. I was sure I was out and now I'm not sure. I'm curious if it is an infection or AF approaching. I went from an average of a 27 CD to a 29 CD and I'm currently on CD 35. I'm afraid to test again just to get another negative or AF comes right after I get the test.
