Can a UTI make you miss periods? I've had 2 UTI's and they have never made me miss my period. I haven't had a period since May 21-25. My breath started getting sore yesterday. I have back aches, and I've had lower stomach aches since June. I mean I haven't gone to the doctor to actually determine if it's a UTI or not, but I posted on here and people said it was most likely a UTI because my urine was cloudy & I was having side pains. But my urine was only cloudy a couple days if that.. I've had some very weird cravings and a lot of discharge too.
