I have been feeling really nauseous and getting fevers for over a week. I started getting back pain and cramping. Sore breasts. I was thinking maybe I have a uti. Since kidney transplant patients are prone to them. I took a test last Thursday and it was positive. I went to a dr and they said. I don't have a uti but my bloodwork indicates some kind of bacterial infection. So I was put on an antibiotic. I can't say I feel any better yet. This almost feels like a flu. But i have had a flu shot. My period is due March 1st and opks( and pregnancy tests)are coming up negative ( i heard they can kind of predict pregnancy given the LH level rise) I have never been pregnant. I don't really think i am because i was told by a dr because of my temp chart that i didnt ovulate.
