Your urine and blood reports indicate urinary tract infection
, probably at higher level. Itching is mostly benign during pregnancy as it occurs due to increased sweating, stretching and raised estrogen levels in the body. Rarely it occurs due to cholestasis
. Protein in urine
in the third trimester along with other symptoms like a raised blood pressure and swelling of the feet is suggestive of preeclampsia
. Since you are in the early mid-trimester, you should suspect infection. I suggest you to see a nephrologist
today and get treated in consultation with your doctor, if necessary by going to the emergency. Good luck.
