Anyone else experience a UTI this late in pregnancy? I went into L & D last night with bad lower back pain and pressure that went into my lower belly and thighs. Plus stronger more frequent contractions. They tested my urine and hooked me up to monitors. Sure enough I was having regular contractions. But then they told me I have leukocytes in my urine which could mean a UTI. Which would explain most of my symptoms. Anyone else get one this late? It almost sent me into preterm labour. I started antibiotics today while they wait for the test results.
