hey angie, yeah definately sounds like a uti...did the doc send the sample off to the lab to see what the organism is? cephalexin is pretty effective on most of them! hope you start feeling better soon! theres stuff you can get over the counter for the cystitis type symptoms you're getting it should make it easier to pee at least and works almost right away...theres one called oasis made by caneston its pretty good..just a drink! hope the ultrasounds are all good xxx
