Cramping? Anyone else?

I've recently been treated for a UTI. Is cramping a symptom of UTI's in pregnancy? I'm thinking maybe the antibiotics didn't work. I haven't had any cramping since early in my pregnancy and I can't remember having any with my other 2 pregnancies. I had a kidney infection with my 1st and was hospitalized for 3days. I now have a 5yr old and an 11mth old so I can't do the hospital thing. The baby's moving fine. But I am having an increased amount of Braxton hicks and the cramps are like a dull ache more annoying than painful.
