Hello dear, I understand your concern. In my opinion the presence of pus cells and blood suggests urinary tract infection(UTI). UTI is most common infection seen in pregnancy.This is due to influence of hormones. Nothing to worry as it will subside with a course of antibiotics. You can as well go for urine culture and sensitivity to know the organism causing UTI and for accurate treatment. So relax.The untreated UTI might irritate the uterus leading to pain and other complications. But if treated it s not going to cause any problem. Take adequate fluids upto 3 litres per day,cranberry juice to prevent UTI. Your blood parameters are also normal as slight variation might be there in pregnancy compared to normal state . Hope this helps. Best regards...Dr.Srilatha
